First of all apologies for the lack of proper terminology I'm a novice Ms Access user and I like to thank everyone in advance for trying to help.
Ok here is the situation:
I have two tables, NewJobs and Contacts which have the following fields.
Newjobs
--------
JobID (AutoNumber, Primary Key)
JobName
JobDate
JobDescription
JobOwner (Linked to table 'contacts' via LookUp)
Contacts
---------
DisplayName
EmailAddress
Department
Extension
Ok basically what I want is to have a form based on table NewJobs which will allow me to enter new jobs into the database. When I get to JobOwner a drop down list linked to 'Contacts' table will show me all the data from column 'DisplayName' and allow me to select it (saves time on typing). I have already done this and its not a problem.
Now I would also like in the same form to have additional fields from table 'contacts' such as EmailAddress, Department and Extension which will autofill with the right information soon after I select a JobOwner from the drop down list.
So for example if I select 'Joe Bloggs' Access will automatically fill the additional fields in the form with Joe's information (department, extension etc) from the Contacts table.
I hope all this makes sense. Thank you all for your support.

I'm trying to achieve something that I'm sure someone has figured out long ago. I have a DB that currently only shows the zip code for certain records. Is there a way that I can have the DB take the current zipcode, reference a zip code table, and then return both the zip and city/state?
Thanks

Code:
DCount("*","[tblLeaveRequests]","Status='Approved' And #" & Format([vDate1],"mm/dd/yyyy") & "# BETWEEN [LeaveStartDate] AND [LeaveEndDate]")
The above code counts all leave with the status of approved on the table [tblLeaveRequests]. Great, but i did forget a critera.
Of the leave it is counting, I want it to only count if the employee the leave is for is in a particular location. which exists on the related table, and not the one dcount is calling.
Is this possible? or will i have to resort to replicated data in [tblLeaveRequests]

Table is named tblLVR
Field is BusinessName
I want to check the previous existence of this name in the table.
I assign a variable tBusVar to the entered name on it's changed event
and write the following code to see if it is already in:-
If DCount("[BusinessName]", "tblLVR", "[BusinessName] = " & tBusVar) > 0 Then
MsgBox "This current record is a Duplicate"
End If
Run_time Error :'2471' : The expression passed as a query parameter produced this error '<Name entered>'

I have a query that currently calculates a rating based on various values entered into the database. This rating corresponds to a Quality Index value based in another table. I tried to set up a query that links the rating value in the query to the Rating in the table, however, when I run this query, I don't get all the results I should. Is there some other way to make this work? I thought it would be simple to link the rating value that is calculated to the rating in the table and have it report the Quality Index value associated with that value. Please help! :confused:

I have a form which have a sub form. In the sub form I have a the direct table to update data on it.
Example:
The form has the name of the project and the subform the name of one of the items of the same project and the table present the documents for the particular item.
The users have the option to add or edir docs to this item.
If I would like to reffer to a value they are entering on this table in VBA . how can I do that?
(I would like to present a msgbox when they are entering a date that isn't right on the table for this item.)
By the way, I can't use validation rule because I have a different dates needed per item.

I have two tables, Table 1 and Table 2 and two related forms, Frm1 and Frm2. I want to be able to update the data on Table1 from Frm2, that is, if I change the data on Frm2, the corresponding fields in Table1 will update to the same data. I know that if both tables are open I can reference the fields on Frm1 and Frm2 with an IF statement: If Active = True And Forms!Frm1a.DoNotchange = False Then..And I know on the update query I can reference a control on a form by Forms!Formname.Control. Wll works fine.What I would like to know is can I reference a table field in the same way. For example, I have tried to use the IF Statement If Active = True And Tables!Table1.DoNotchange = False Then..Is there a way to reference the Table instead of the Form in both the VBA and the query? The problem seems to be that I have the two bound controls [Active] on Frm2 and [DoNotChange] on Frm1. (Which I need).

I would like to update two fields [Category] and [ProdType] in tblAccum based on a reference table.
The reference table is tblReference and contains the fields [Code], [Category] and [ProdType].
tblReference example of field values:
Code Category ProdType
A Blank Accessory
BS Blank Blank Stock
O Printed Offset
So if the Code field in tblAccum has a value of O then based on the tblReference table the Category value would be Printed and the ProdType value would be Offset.
Any help is greatly appreciated.
Thanks,

I reused one macro to develop a form in MS access.
The macro fetch the record set corresponding to the reference value from the table.
The reformat value is a numeric field.
The macro code is :
Private Sub Modifiable20_AfterUpdate()

Set rs =Me.Recordset.Clone
rs.FindFirst "[Reference_Number] = ' " & Me![Modifiable20] & " ' "
If Not rs.EOF then Me.Bookmark = rs.Bookmark
End Sub
What to change in the above code to make it work....

I am working on an form (using Access 2000 and VBA) that stores registration information, along with events that were attending, in a table and later retrieves that same information from the table to display the regist. info, events attended, and allows the user to change any current info along with adding new/recently attended events to each record.
I am currently allowing a max of six events, along with event details, to be stored and I am running through six different if statements to match the Event_List (name of the combo box that contains "Event 1 Event 2...Event 6") to the appropreiate information in the table. I have started to simplify the code to remove the redundancy by running a Do While to to find the correct Event by using an integer variable that starts at 1 and is incremented until it matches the 7th character (the number portion) of the Event chosen from the Event_List. After this I want to use that integer variable to say what event information in the table to gather. My problem is this: I have tried many different varieties of the following code and I am unable to make it work. I had never used Access up until a week and a half ago, and a few days ago I went and bought the book "Access VBA Programming for Dummies" but it doesn't help for this problem. Here's part of the code:
Variables (Event_Name, PMT, Receipt, Payment_Type, PIF) refer to Form textboxes while the variables in the [] refer to table field names.
'------Code I'm Currently Working On-------
Dim intX As Integer
Dim EventVal As Integer
Dim strX As String
intX = 1
EventVal = Val(Mid(Event_List, 7, 1))
Do While EventVal <> intX And intX < 6
intX = intX + 1
Loop
strX = str(intX)
Dim E_Name As String
Event_Name = [Event strX ]
PMT = [PMT strX]
Receipt = [Receipt strX]
Payment_Type = [Payment Type strX]
PIF = [Paid In Full strX]
'-----Old Code That I'm trying to simplify-------
If Event_List = "Event 1" Then
Event_Name = [Event 1]
PMT = [PMT 1]
Receipt = [Receipt 1]
Payment_Type = [Payment Type 1]
PIF = [Paid In Full 1]
Camp_Site = [Camp Site 1]
Cabin_Number = [Cabin Number 1]
ElseIf Event_List = "Event 2" Then
Event_Name = [Event 2]
PMT = [PMT 2]
Receipt = [Receipt 2]
Payment_Type = [Payment Type 2]
PIF = [Paid In Full 2]
Camp_Site = [Camp Site 2]
Cabin_Number = [Cabin Number 2]
ElseIf Event_List = "Event 3" Then
Event_Name = [Event 3]
PMT = [PMT 3]
Receipt = [Receipt 3]
Payment_Type = [Payment Type 3]
PIF = [Paid In Full 3]
Camp_Site = [Camp Site 3]
Cabin_Number = [Cabin Number 3]
PLEASE HELP!!!!

I am trying to see if it is possible to store colors in a form or table and then reference them while in VBA. What I am hoping to do is when I write all my code for command buttons to change On Got Focus, instead of writing xxx.backcolor = RGB (255,255,255) i could do something like xxx.backcolor = Forms!HiddenColors!Command That way if i want to ever change the color scheme of the db, I can change it in one place rather than hunt lines of code.
I have played around but with no success.

Can an Excel spreadsheet reference an Access Table for it's data? Sort of like a vlookup, but instead of referencing another spreadsheet, I'd like to pull data in from a database.

In my form (source tblJobs) i input a contract number from tblContracts. but i would also like it to show the contract address when the contract number is entered. Both fields belong to tblContracts but i only wish to enter the contract number, the address will just be used as a reference as it isnt something i would have to enter again.
So for example
112 - Main Road
If i enter 122 in my ContractNo field i would like it to show the contract address for that specific contract.
Can i do this? If So how?

Currently running Access 2010.
I have a small database where we enter audit log data. In my add add screen from the switchboard, one of the fields is the user the audit is assigned to. So that our group wouldn't be typing their names a bunch of different ways I created a reference table called "Ref Data 005 - Contact Name". So i pre-populate the Contact Names such that they will be more consistent.
The add works perfectly. I built all my screens using the forms wizards.
Now for the modify routine. If the user wants to go in an modify one of the other data elements, I force them in the wizard to do this modify by choosing thier name. Therefore, when i built this screen using the wizard I reference the "ref table" mentioned above. I then throw open another form displaying all of the fields based on the records that it finds for that user when they choose the name from the Ref data 005 table. Hope that makes sense. Ie.. they choose the records they want to possibly modify by first choosing their name from the ref table.
It correctly pulls the records for whatever user you choose. However, when you make the update and save, it is changing the Ref table name as well.
So for example if three users were in my ref as :
bill
joe
john
And you launch the form, lets say joe shows up in the list, when i change it to bill to retrieve bill's records , it will do that but when i make the change, then Joe is changed to bill in the reference table.

I have a table I'm trying to query information out of. Key fields are below:
RecNo (Key)
ParentRecNo
Description
I need to have a "record" in the query show both the description of itself, as well as it's parent. I was hoping to use Dlookup directly in the query design. If there is no other way, I suppose I could create a temp table and look through the recordset in VBA and dump them into the temp table, but like I said; quick and dirty was the hope here, it's for my own use, and the tables aren't large 50-100 records is what I'll be pulling out when I use this.

Was wondering if someone could possibly help me with a DCount problem i'm having.
I have a form with a subform, displaying bookings that customer has made. What i want to be able to do, is when a booking is created for a customer in this subform, after the time period chosen is selected, i want a DCount to run, go to a table of regular bookings, count up how many bookings in it have the date of booking, that same as the date just put into the subform, AND the time period of booking the same as just put into the subform. There can only be 1 result at max due to its setup, and from there it should be fine, but i cannot get it to work. The field names are as follow:
Subform:
Date for Booking
Time Period
tblRegularBookings
Date For
Time Period
If this doesn't make any sense i can try and explain better.
Can anyone help me?
Thanks very much in advance

I have only been using access for about 3 weeks now, and its kicking my butt pretty hard.
Im making a query that does all kinds of math junk in it. I want to be able to find the number of occurrences of x in another column in the table.
For a better example, lets say I have a column named "SP" in the "compiled" table, the values of this column range from 1 to 5, in about 200 entries. So there is another column in the compiled table called "SPX", which has the same value range. So if I am looking at the one entry in the table, I want to take its value in the "SPX" column, and see how many times it shows up in the "SP" column.
I have been trying to get dcount to do this, but I cant seem to get it to work... Must have tried a dozen ways now.
Any help would be awesome, thank you.

My main table is called NEWcompiled, I have fields named "faction", "SPeffect", and "Launcher_ID". I am trying to use Dcount in a query to count up how many entries have a value in "faction" and "SPeffect" that are equal, and a value of "yes" in "Launcher_ID".
Currently my code looks like this:
DCount("Faction","NEWcompiled","Faction = '" & [SPEffect] & "'" And "Launcher_ID = yes")
This indeed counts how many entries have equal values for "faction" and "SPeffect", but then it seems to add that to sum of all the entries that have a yes for "Launcher_id".
Any help would be great, thank you for your time.
