DLookup() In A Form
Feb 14, 2005
Implementation of the DLookup() function is still giving me fits. The syntax I use is:
=DLookUp("SecText","tblDocSections","tblDocSections!SecCode = & forms!frmTestA!SecCode)
The function returns a null except for certain values of SecCode. The value of SecCode ranges from 0 to 99999999. Some values of the code work but most do not. When I do get text returned, it does not match the document section. Is there a counter that needs to be reset or re-indexed?

I have searched for days and not been able to find an answer to a supposedly easy question.
I have a continuous form "Entry_Form" based off a table called "Today". I want to add additional criteria to the table using the form and have created a combo box that is based on a separate table called "Reason_Codes". "Reason Codes" has two fields "ID" and "Description".
When selecting the combo box "ID_Selector" I populate one of the fields on the form which then populates the corresponding field on the table. This works.
My problem is that I want to have a text box on the form called "Description_Code" populated automatically the "Description" based the ID chosen.
I have created the following DLookUp equation and placed it into the Control Source, but nothing is populated in the "Description_Code" field.
=DLookUp("[Description]","[Reason_Codes]","[ID] = Forms![Entry_Form]!ID_Selector")
Needless to say, I have tried dozens of varieties, but to no avail. Is DLookUp the proper function? What am I doing wrong?
Any help would be greatly appreciated.
Thank you,
Shawn

I know to most this is simple, but as a newer user putting everything in its right place is hard. Have checked multiple posts for my situation and cannot locate. I know I need to use DLookup.
Membership table used to built form has among others, a contract #1 field (9-digit Soc.Sec. #) and a Contract #2 field with another randomly assigned 9 digit number. Current form set up to accept contract#1 in an unbound text box which then autopopulates other fields pertnent to this member. Member should be giving us Contract #2 but that will not always happen. Want a DLookup so that if the #1 num is put in it will automatically input the correct #2 number.
Not sure where to put it and exactly how to format. Can someone please help me. Both fields on the same table.

I am having an issue with trying to display text data "Supplier-ref-1" from a Table called "Supplier Prices" which also has the "Item-code" field. I want to display it in a text box in my "Items" form, where the Item-code is equal to that in the Supplier-prices
=DLookUp("[Supplier-ref-1]","[Suppliers prices]","[Suppliers prices]![Item-code]='" & me.Item-code & "'")
Everytime I enter this into access, it modifies it to:-
=DLookUp("[Supplier-ref-1]","[Suppliers prices]","[Suppliers prices]![Item-code]='" & [me].[Item]-[code] & "'")

I'm using Access 2010. I'm having trouble with dlookup.
Table name: tblTier2
Fields: Tier2ID, autonumber
Tier2FieldType, text
I have an unbound list box on a main menu form.
The listbox control is numeric and called: lstItem
I tried putting the following in the textbox:
Neither of these worked:
= DLookUp("[Tier2FieldType]","[tblTier2]","[Tier2ID]=" & [lstitem])
=DLookUp("[Tier2FieldType]","[tblTier2]","[Tier2ID]=" & [lstitem].[column](0))
I wanted to see if the lstItem was the problem, so I put ths following in the text box. :
=[lstitem] (it returned the ID number selected from the list box, e.g., 809)

I have created a frmOrder form that uses autofill fields using dlookup when a company name is selected from the cboCompany combobox.
However!
I noticed that the value that has beed retrieved from dlookup function are not stored in the table (tblOrder).
How can I achieve this?
I have written the code in the control source of the field (in this case: LastName field) in the form like this:
=DLookUp("[LNamePIC]","tblCompany","CompanyID=" & [cboCompany])
The DLookup works fine, just I want the value to be stored in the table. Please help me ! I have been browsing the internet for the whole day and i can't seem to find the right solution!
Thanks!

This is my code.
=DLookUp("[ItemDescription]","MasterData","[BarcodeID] = " & [Forms]![frmMasterData]![Barcode])
I have a from called "TakeOn". The from is based on a table, called "tblTakeOn" with fields ID, Barcode, ItemDescription and SerialNumber.
In the form "Take On" is is a combobox named barcode, that looks up the bacode values from a table called "MasterData".
The "MasterData" table has only 3 fields, ID, Barcode and ItemDescription.
I want to in the "TakeOn" Form to, in the ItemDescription Field, display the ItemDescription from the ItemDescription value in the 'MasterData" table.
Access displays a circular reference error message.

At the moment I have a form (InputFrm) for operators to enter production processes into the system. Each one of these has a certain weight which the operators enter and it all stores in InputTbl, which works great.
However I am trying to have a running total of the kilograms inputted on each day displaying when a new record is opened. To do this I have created a query (DailyDataQry) which provides me a running sum of how much input has gone through the process, and I can clearly see the data in this query.
I am attempting to have a text box in the upper right of my form which displays this number as after a certain weight of input the operators are needed to perform checks.
This is the code I have at the moment in the control source of a text box (DailyInputTotalTxt), but it is just returning a blank:
Code:
=DLookUp("[Total Input]","DailyDataQry","[Work Date] = #" & [Forms]![InputFrm]![WorkDateAtxt] & "#")
The work date is generated automatically when the new record is created by having Date() in the default value of the work date (WorkDateAtxt) on the form.
Is there any way which I can use this value to lookup the current total of input contained within DailyDataQry?

I'm making a form for colleagues to use which will eventually populate a table. I'm using DLookup to populate some of the fields in the form from another table. The problem is that for a few of the fields in that other table, the values are incorrect.
(Obviously the most sensible thing to do would be to amend the source data but for various reasons I cannot do that.)
For example, "date built" in the original table might be "f" but that needs to be changed to "h", so I tried the following but it doesn't work:
.................................................. ............................................
If DLookup("date_built", "dbo_meas_questionnaire", "[meas_id] = Forms!FrmRetestSearch.numOrigId") = "f" Then
Me.TxtDateBuilt = "h"
Else
Me.TxtDateBuilt = DLookup("date_built", "dbo_meas_questionnaire", "[meas_id] = Forms!FrmRetestSearch.numOrigId")
End If

Here goes my problem, and how I am attempting to solve it, but I am open to advice.
I have a table that contains all of the bird species in the US; (fields: common name, scientific name, species ID) I want to be able to update another table, (birds to chase) with particular bird species that I have not yet seen, (fields: species ID, common name, scientific name) and link that to a sub form that links to another table (chase birds locations) which shows geographic location data as to where I might be able to see new/unseen birds; (fields: species ID, date, other geographic data).
My problem is this. I created a form for the unseen birds table that allows me to only select a bird using a combo box of birds from the larger table of US birds. I want to select a bird using the common name in this box, and have it automatically populate the scientific name and the species ID into the birds to chase table. I link this tables to the location table using species ID.
A workaround that I have used is to close the form, run two update queries that populate the proper fields for scientific name and species ID and to re-open the forms. Although this works, when I return to the form it does not return me to the proper record, so that I can enter data into the sub-form.
Obviously this is a workaround and will work for me in the short run, but I want to learn how to do it properly within Access 2003.
I'm not a programmer and hence do not have access to the .NET tools or Visual Basic. Any hints for me out there?

How do you refresh all of the data on a form when the tables that are the source for dlookup fields on the form are changed by command buttons on the form?

I have a DLOOKUP which is used to auto populate a field on my Income Commitment Form based on a field on my Expenditure Commitment Form.It works perfectly when you enter a new commitment.Currently you enter a new Expenditure Commitment, save it but don't close it, then from the Expenditure Commitment Form there is is a button to enter a related Income Commitment. You save the Income commitment then close it, then close the expenditure form and you are on the Client screen with both these forms now showing as subforms, both have record selectors.
My issue is, that sometimes the Expenditure Subjective can change, so from the client form you use the record selector to open the Expenditure Commitment and select the correct Subjective, you then save it and close it. You should then click on the Income Record selector which opens the income commitment, but when you re-click on the Combo42 button, it doesn't reselect the Income subjective and I think it is because the Expenditure Commitment which is what it is looking up isn't open. My issue is how do I get the DLOOKUP to work and refer to the Commitment Form if it is a new commitment, or the Subform if I have gone back in through the record selector.Here is the code I have.
Private Sub Combo42_AfterUpdate()
If (Me.Combo42 = 1) Then
Me.IncomeSubjective = DLookup("[Subjective]", "tblIncomeSubjective", "[ExpSubjective]='" & Forms![frmCommitments]![cmbSubjective] & "'")
Me.OtherIncomeConfirmed.Enabled = False
Me.OtherConfirmedBy.Enabled = False
[code]....

So I'm working on something for housing. Each house has a "Property Reference". This property reference links to all other information on the property.
There's two tables, Referral (For a tenant, with the Property Reference as a foreign key) and PropertyInfo (Holding all the property information)
Basically I want to save users as much input time as possible, so I'd prefer if they could just enter the property reference for a person, and that populates the rest of the table.
I'm currently using DLookup on the main form where it displays the information related to the property reference, obviously it's not actually being saved into any fields.
Will this method be okay if I would want to search the records by the address on the main form?

My intentions are to get my combo box to display data into a field in my form, when it is changed/selection is made. So far my form has the following:
Combobox: CBOCharacters
Field: CharacterGender
Both of these are in the same table; tbl_Characters. The data type for CBOCharacters is a number and its called CharacterID in the table.
So far I have created this piece of code:
Private Sub CBOCharacters_AfterUpdate()
Me.CharacterGender = DLookup("CharacterGender", "qry_StillNeeded", "[CharacterID]= " & Me.CBOCharacters)
End Sub
When I run this event procedure i get an error:
Runtime error '2471'
The expression you entered as a query parameter produced this error '[CharacterID]'

I have a simple data entry form based on a table. However I have a few fields that I do a lookup in a field on the form from a query, and yes I know I should not have a lookup in the control source however, this is the way that I will be doing it on this occasion.
=DLookUp("[Salary]","[Salary Query]")
How I get the value from this unbound field to enter into the actual field in the table. Do I bring the actual field into the form and hide, and do some sort of after update, as I have tried and it does not work.
I have called the unbound field with lookup "Salary Level Base" and the actual field in the table is "Salary Base".

I am working with a database that I downloaded and am trying to modify to fit my needs.
This is an inventory database. The products table contains a description and pricing. I want the description and pricing to populate in the Purchase Order form, so I added Dlookup fields in the Purchase Order form. I was happy.
However, the pricing information is not populating to my Inventory Transactions Table from the Purchase Order form by way of this Dlookup feature, and therefore will not show on my report, and in turn does not show in my Total of my Purchase Order report.
As a work around, I tried creating a calculation in the purchase order report, of =[UnitsOrdered]*[Products.UnitPrice], and the pricing totals show fine on my report, but the subtotal doesn't work.
I was unable to upload my file...so a few notes of info...
There are no queries set up in the database for this report.
I had tried a sorting grouping thing (in the Report) by Subtotal, but now can't get rid of it.
When I show the field list for the report, across the top of the window reads:
SELECT DISTINCTROW Employees.*, Products.*, [Inventory Transactions].*, [Purchase ORders].*, Suppliers.*, nz([Inventory Transact
Looks like it runs out of space
I am trying to attach a couple of images to support my comments.
Since this issue crosses both reports and forms (and tables!), I am not sure where to properly post. The end result I am looking for is on my report.
I am using Access 2003...

Having problems getting dlookup to work in the control source field of a text box.
My form has fields : Catalog # (numeric value) and Country (drop down text selection).
I would like to query a table CatNameList for a name (text) if the catalog # and country find a match on the table.
My field names on the CatNameList table are : Name, Number (to validate against the Catalog # entered on the form) and CName (to validate against the Country drop down on the form).
I am successfully able to populate the name from the CatNameList table on my form using lookup of the catalog # using this :
=DLookUp("Name","CatNameList","Number = Form![Catalog #]")
However, I will eventually have several catalog numbers that will be identical in the table CatNameList, thus why the country is important as the second criteria to be added into the dlookup.
I have tried for a few hours unsuccessfully to add the second portion to my dlookup.
This is what I have currently (not working) that I have been playing with, I'm sure I'm missing a quote mark, & or something simple.
=DLookUp("Name", "CatNameList", "Number = Form![Catalog #] And CName = ‘”& Form![Country] & ”’”)

basically am creating a booking system, i have a add a room form. my form should check whether i already have a room number in my table, which works when the form is filled in. however when my form is null, then i press add new room button, i get this error rather than " please fill your form in"
Error: runtime error '3075' syntax error (missing operator) in query expression 'Room Number ='.
room number is a number field, integer but has primary key. i cant keep autonumber, as my requirement is to add new room number, but the roomnumber has to be unique.
here is the dlookup;
If DLookup("RoomNumber", "tblRooms", "RoomNumber = " & Forms!RoomPackages!txtRoomNumber) > 0 Then

My db has 4 tables and forms
Table/Form 1 contains customer information: ID, Name, Address and Contact Numbers
Table/Form 2 contains vehicle information: ID, Vehicle Model, Plate Number, Chassis and Engine Numbers
Table/Form 3 contains insurance coverage data: ID, Plate Number, Policy Number and details of insurance coverages
And Table/Form 4 contains premium collection data: ID, Policy Number and details of payment
The underlined fields are the respective primary keys and relationship of each table.
I want the Plate Number on Table 3 to automatically change, once the user edits the same field on Table 2.
My concern is, if the customer has 2 or more vehicles or plate numbers, the DLookup function only takes up one plate number. How do I use this function without compromising the relationship of the form???
My other concern is the =Right([PlateNumber],1) function I used on my Ending Plate Number field. Data appears on the Form but if I look on the Table, data is missing.
Cant figure these out! Please help..
Thank you!

Can anyone see where I've gone wrong. The purpose should be if the value in the query is 0 or less (a minus amount) and the order number and part number matches the order number and part number on the form then a warning should appear. It's not picking up the record for flagging when it should:
If (DLookup("OutstandingQty", "qryremaininginvoiceamount", "OutstandingQty <= 0" & " And [OrdNo] = " _
& Me.[OrdNo] & " And [InvPtID] = " & Me.InvPtID)) Then

Hi,
I am pretty new to Ms Access.
I have a table which has a list of trades (Builder, Carpenter, Painter etc) going down the side and going across the top I have the number of employees (1Emp, 2Emp, 3Emp). The values in the table show the charge for that number of employees for that trade.
I have a form which has three combobox's that show the Number of Manual Employees, Number of Clerical Employees and the number of working directors and a combo box that shows the trade. What I want to happen is when the user clicks a command button on the form the charge for the total number of employees for that trade is shown in a txt box.
I have the following code attached to my button:
Private Sub GetValue_Click ()
Dim TotalEmployees As Integer
TotalEmployees = [NoManual] + [NoClerical] + [NoWorkingDir]
Value = Dlookup(TotalEmployees & "Emp", "ValueTable", "[Business] = Forms![Form1]![Business]")
End Sub.
When I type "[3Emp]" in the Dlookup it will work fine and finds the charge for that trade. But when I pass it the Result from the addition and concatenate it with "Emp" it doesn't seem to work.
I originally thought it was because I declared the TotalEmployees as an Integer by I also tried declaring it as a string - to no avail.
I just can not figure out why it will not look up the TotalEmployees.
I would much appreciate any help on this on any suggest as to how I can get the values from my table.

Please help prevent my laptop from being smashed against a wall numerous times and then being thrown out the window, after all, the wall is mostly innocent in this situation.
I have read post upon post and other dim references to DLookup in the Access Help file, etc. I am generally a bright guy (although inexperienced in DataBases, VBA and some forms of lovemaking) but I have not been able to figure out the DLookup function. Could you please give me a VERY simple explination of how to use this function and it's expressions?
If it will help, we can use the following senario...
Table_Special_Needs
Special_Need_ID
Special_Need (Data Includes: Initiatives, High Ropes, etc.)
Standard_Price
Table_Event
Event_ID
Initiatives
High_Ropes
Extra_Linens
I would like to be able to add a price field for each item in the Event table and have the table lookup the price from the Special Needs table.
Many thanks for any help you can give.
