DCount On Form - Error
Oct 27, 2005
Hello,
I am trying to set up a statistics summary of my database. Part of this is the number fo records counted in a query for various queries. I found this on the forum:
To show the number of records returned by a query, you can use the DCount() function.
Put a text box on the form. Put this in the Control Source property of the text box (using the correct query name):-
=DCount("*","queryName")
I have made a blank, unbound form and added a text box using this syntax above (with my query name).
However, I get an error in the box '#Name?' when I run the form.
Any suggestions?

Hello,
I am trying to count the number of records in the query result and for some reason, it's not coming up with a number. This comes up "1E+0.."
not sure what's really going on, but this started happening after i converted all my data from excel. However, records come up when i actually go run the query and not from the form.
here's my formula from the form:
=DCount("[Queue]","qryODFData","[Queue]= 'NBCT'")
I'm sure some of you have ran into these problems after data conversion.
Does anyone know what it could be?
Thank you

This is my string to calculate the next increment # based on request date and users initials.
However, I get the #NAME? error when I run the form?
=DCount("[INCR]","tblPURD","[reqdate]=" &
Format(me.txtreqdate,"#mm/dd/yyyy#") & " AND [initials] = '" &
me.txtinitials & "'")+1
Any help will be appreciated.
Thanks.

In order to prevent a duplicate values in the field TR_Tripcode (text) I put the following code in the Before Update Event of TR_Tripcode.
************************************************** ********
Dim SID As String
Dim stLinkCriteria As String
Dim rsc As DAO.Recordset
Set rsc = Me.RecordsetClone
SID = Me.TR_Tripcode.Value
stLinkCriteria = "[TR_Tripcode]=" & "'" & SID & "'"
If DCount("strTripcode", "tblTripreports", stLinkCriteria) > 0 Then
'Undo duplicate entry
Me.Undo
'Message box warning of duplication
MsgBox "Warning Tripcode " _
& SID & " has already been entered." _
& vbCr & vbCr & "You will now been taken to the record.", vbInformation _
, "Duplicate Information"
'Go to record of original Tripcode number
rsc.FindFirst stLinkCriteria
Me.Bookmark = rsc.Bookmark
End If
Set rsc = Nothing
************************************************** ********
I found this code on a site and I adjusted it for my situation.
However I keep getting Error 2501 'You canceled the previous operation'.
Even after reading all posts about this subject I still haven't figured out the problem.
All suggestions will be greatly appreciated.

Just wondering if anyone knew how to help me out, the weird thing about it is that it has been working for a few months.

I am trying to use DCount to count the number of records (speakers) for each session. Not being very savvy with DCount, I copied code that I had working for another instance of needing to count the number of records.
My query has three fields
Query used: Web/PrintReport_qry
Session Id - number
Speaker - string
Code:
SpeakerCount: DCount("*","Web/PrintReport_qry","[Session ID]='" & [Session ID] & "' And [Speaker]<" & [Speaker])+1
My output for SpeakerCount is "#Error"

I ahve declared custCount as an integer and id as a string that comes from the user form (id = me.CustID) and trying to count the number of matching records in the recordset (rst) using the following:
custCount = DCount("[customerId]", rst, "[customerId] like '" & id & "'")
I'm getting a type mismatch error on the DCount statement?

Hi,
I'm trying to use 2 criterias for this dcount function but I get "type mismatch" error. What I want to do here is, if the model (from model and to model) is not existing, activate a new form). Any help will be appreciated. Other alternative methods are welcome as well.
Thank you.
Private Sub REF_Enter()
Dim OUTx As Integer
Dim INy As Integer
OUTx = DCount("*", "STDCONVOUT", "[FROMMODEL]='" & Me.[FROMMODEL] & "'" And "[TOMODEL]='" & Me.[REQUESTMODEL] & "'")
INy = DCount("*", "STDCONVIN", "[STDCONVIN]![FROMMODEL]='" & Me.[FROMMODEL] & "'" And "[STDCONVIN]![TOMODEL]='" & Me.[REQUESTMODEL] & "'")
'OUTx = DCount("[PARTNUM]", "STDCONVOUT", "[STDCONVOUT]![FROMMODEL]='" & Me.[FROMMODEL] & "'")
If (OUTx = 0) And (INy = 0) Then
If MsgBox("This is a new model. Add this model?", vbOKCancel, "Error!") = vbOK Then
DoCmd.OpenForm "AddConvModel", acNormal
End If
End If
End Sub

I have a subform which displays details of an Insurance Certificate. Upon or near Expiry, a Letter is created to remind the Broker. I'm using the following
=DCount("[LetterID]","InsLetters"," [InsLetters].[InsCertID] = Forms![subInsurance]![InsCertID]")
in a textbox recordsource to count the number of letters which have been sent out for a given Cert., so User can then click to display a summary of those letters.
The subInsurance form is a Sub on a TabCtrl on a main form 'Aviation'. When I got through the Aviation form, it displays an error... but then corrects when I open the subInsurance form directly, but Users will not wat/be able to do this.
How do you get round this? Please.

I have a form that is linked to a query by its Record Source.In one of the Text boxes I want to appear the number of rows in the query where Days = 4 so I thought I would try to use DCOUNT as the Control Source for the Text Box. However every expression I try for DCOUNT throws back error? or name?. How to sort my code?
=DCount("[EPISODEUNIQUEKEY]","1-12 Show Records by Date Range","[Days] = '4'")

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.

I've looked at numerous threads on this site and still can't get a dcount to work.
I want the database to check if there is a valid reference number entered before opening a form.
There is a table called 'staff' with a 'payroll number' field in it. This table contains all staff.
I then want the user to enter a payroll number and retrieve the corresponding record. However, if there is no match then the user has entered the number incorrectly.
I've done:
int2=dcount("[payroll number]","staff",forms!control,payroll) and then an:
if int2=0 then msgbox
end if
exit sub
However, I either now get a message when the number is correct, or it's exitting the sub every time.
Any corrections please?

What I want is for DCount to see how many times a a Box# appears in a table, if it is 0 it puts a message up that the box does not exist.
This is what I have as the code
If DCount("[tblLockbox]![LockboxNo]", "[tblLockbox]", "[tblLockbox]![LockboxNo]=" & Me.[txtGLockbox]) = 0 Then
MsgBox "Lockbox not Found! Please try again.", vbCritical
Me!txtGLockbox.SetFocus
End If
tblLockbox is the table that contains all the lockbox numbers and the names they relate too.
LockboxNo is the field that holds the Box#. I have the field set as a Text because no calculations are done with these values.
txtGLockbox: is the field on the form where they enter the Box#
The problem is I keep getting a data type mismatch in criteria expression.
I thought DCount took a count and returned a value, so it shouldn't matter what data type the field in question is.
We are using it in another area where the field in question is a number.
I hope this makes sense.

I've been back thru this DCount function, here in the forum and elsewhere. I have posted about this function before and even went back to my old post. Looks like I still need some help.
Here's the premise:
My database has a query that tracks Payments made to Students who are on the Federal Work-Study program. We have 4 categories of work: On-Campus; Off-Campus Community Service; Off-Campus Family Literacy; College Support Services.
Of all payments made to students in the year for Federal Work-Study, there are some payments in each category. On the Report, based on the query "FISAP Detail Query", programmed to show every disbursement(payment), I'd like a count of each type in the Report Footer .
I have a control on the report that I'd like to use to count the number of students paid for Community Service.
=DCount("[StudentID]","FISAP Detail Query","[Community Service Amount]>0")
and I've tried
=DCount("[StudentID]","FISAP Detail Query","[Community Service Amount]>'0'")
Count the number of students listed in the FISAP Detail Query who have a [Comunity Service Amount} greater than zero. Sum totals of disbursements for the year for each student are displayed in the Detail section of the report as a single record. So how many of these records have Commuity Service disbursements; that's what I'd like to know.
The formula returns #Error.
Anybody have any advice for fixing this? It must be some syntax or trying to use the wrong function to do the job.
Any help will be very much appreciated
Cheers!

Ok, I admit that I know just enough about Access to be dangerous, so maybe I'm going about this the wrong way... I'm trying to set up what seemed like a relatively simple Query, but for whatever reason it's just not behaving in the way I thought it would.
We're attempting to set up a database to track sales of product, as work orders, then take that data and reorganize it through Queries for use in our payroll system.
I have the tables, queries and forms set up to enter in our work orders just fine, and there are no issues there. The problem comes when I attempt to re-query that information for use in the payroll side. Here's where I sit at the moment:
I've built a query which pulls data from the [Work Orders] table, using criteria which filters out data one employee at a time, for certain invoice dates, for only certain status codes - the ones which are payable on this payroll week. Then, I built a form, [Payroll1] and added a few fields in it which *should* pull from [Payroll1]![ProductSold] field, and count the number of instances of, say, "Digital" product, tally that number using the DCount function, and display that number on the form, for later data manipulation. It all looked good, until I actually ran the form and instead, recieved an "#Error" in my newly created field, instead of the tally of "Digital" that I expected. Am I using the function DCount wrong, or is there some other relationship that I'm not understanding here?
Thanks in advance!

I have a DCount() statement that checks to see if records (in a qryCheck) meet that condition. I have it where if DCount(…) > 0 then do something.
What I would like to be able to do is to display all records where conditional DCount() check = 0 on a certain form.
Is this at all possible? I can't seem to figure out how to do:
Show all records where DCount(...) = 0.
Thank you.

Im trying to count the number of records in a table in a certain field that match a certain criteria.
I've tried to figure out how to use Dcount with some success, but only in counting total records.
Here are two examples. The first one didnt work.
=DCount("RegisteredAt","tblGlobalReg","RegisteredAt=003 - Orland Park")
RegisteredAt is a FIeld name in the table tblGlobalReg.
RegisteredAt=003 - Orland Park is my criteria.
The second one, with out criteria did work.
=DCount("[RegisteredAt]","tblGlobalReg")
I guess my question is, how do I insert criteria?
