Issue when summing fields containing Iif expression

[howardt]

Ok, long time viewer, first time poster:

I have a list of Bank presentations, each has a specific dollar amount.

Before the Presentation is accepted by the bank the Amount Accepted field returns 0.00.

When it is accepted the Accepted? field is checked and the Amount Accepted field returns the specific amount for that Presentation. This bit is fine and is done by the expression:

Amount Accepted = IIf(([Accepted?])=Yes,[Amount],0)

The issue arises when I need to sum the all the Amount Accepted values. Hence when I have my calculated control in the footer of the subform with expression:

SumofPresentations = Sum([Amount Accepted])

It returns #Error. The eternal question: WHY?

IIf([Accepted?],[Amount],0) worked for me

Thanks for the reply NullZero.

The issue is actually related to Access not storing calculated values, discussed in detail in the following link.

Hello and welcome to MrExcel.

I haven't tested this but have you tried using something like this:

=Sum(IIf([Accepted?],[Amount],0))

Hi Andrew,

Your code works fine in the subform to give me what I need
=Sum(IIf([Accepted?]=Yes,[Amount],0))

Then when I try to repeat the calculation in the main form with:
=Sum(IIf([Presentations subform].Form![Accepted?]=Yes,[Presentations subform].Form!Amount,0)).

I get my same old #Error. Any ideas why?

Hi

You can't directly reference the items on the subform like that but you can reference the total on the subform. To see how to do this, follow this link for a full blown explanation.

HTH, Andrew

Andrew,

Thanks for your help, the issue was confused as I hadn't told the form to refresh.

All done to my satisfaction now though.
