Hi community experts,
I am having an isue with Dsum function that is used to count the total number for a particular field (intake) at the textbox afterupdate event with condition/ criteria (subject). Below is the scenario in details.
What I need to do is summing the intake corresponding to what is selected from the dropdown combo box. For instance if the user choose maths in the combo box, the total no of intake should be displayed in the subject textbox as 150.
May I knw hw can that be achieved and whether I am in the correct direction? I have provided the necessary details that is required for this scenario. Tks for advice, code snippets.
Form controlSource = Registration Table - Registration Table design view

SerialCode autonumber primary key
-
subject text
-
intake number

SerialCode Subject Intake
-

2 science 100
-
3 maths 50
-
4 science 50
-
5 english 100

- Form design view

-
Subject unbounded combo box
-
Subject unbounded textbox
-
Intake unbounded textbox
Code - Private Sub Subject_AfterUpdate(Cancel As Integer)
-
Dim sum As Variant
-
sum = DSum("Intake", "Registration", "subject = '" & Me.ComboSubject.Column(0) & "'")
-
Me.Requery

End Sub

Your code doesn't seem to know what the control is named :
Private Sub Subject_AfterUpdate but later on :
Me.ComboSubject.Column(0)
Also, after setting up the variable Sum it doesn't seem to use it anywhere.
tks for the reply. issue has been solved

I'm using Access 97 and need some assistance in sorting out a proper
DSum expression, or maybe even DCount might be an alternative. I have

The DSum function relates to a subform (sfrmCost) with a text box
(RefCost) which is intended to be the container for a total from a
query (qryItems). The query has three number columns from the table
(tblItems) of which I have an expression...

All,
I have never used this function before and am not sure it what I need.
Just to clarify, I have a report based on a query which has amoungst other
field, wk, parea & packs_req. What I am trying to do is create a subreport
for the main report which gives a generalised breakdown of the main report.
For the gender of 'Ladies', there may be several parea's so I want to sum
the packs_req for ladies only. (Gender is not a field I can use,...

I would like to calculate a total for all the field with the same
in a query.
I don't know how to set the "criteria" for this dsum function, it should be
something like = but it doesn't make sense.
The query is something like:
+-- --- ---- ---- --- ---+
+--1-----Alpha-------a1----------------1------------4------------------+
+--1-----Alpha-------a2----------------3------------4------------------+

Good morning all:
In what seems like an ongoing saga to make the DSum function do what I need it to, I am now having trouble with a user-defined function in my VBA module. Here's the offending line of code:
Me!txtLostDaysNoPaySeasonal = DSum("getNumberOfWeekdays(!, !)", "qryTest", "! = 'BK21312'")
In this, getNumberOfWeekdays is a function that I define elsewhere in the module, as such:
Function getNumberOfWeekdays(dteStartDate...

Hi,
I'm trying to use a variable "FirstSemi" as the second criteria in a DSum function. The DSum function is used in the same Form_Load function that the variable was declared. I keep getting an error referencing the variable in the DSum function when the form loads. Any ideas?

To start, here is my DSum expression:
Develop: Nz(DSum(". & "] + . & "]","CSO","='Ability to Develop'")*-1,0)
I actually have 4 of these, each one with a different option for .
For more context, the . part is drawing from a separate reference table which cycles through plugging in the name for each DB_ and Ben_ field in the CSO table.
What I want to do is add another layer of criteria, the field which exists in the same CSO table. I'd...
