IIf Problem

[Ciggys]

Hi all

Just been for a surf around the net looking for answer to an issue i am
currently having with a formula in a query in access
I am trying to get the gst factor of a product using a YES/NO combo box has
the control sauce.
The sum i have in the query looks like this
IIf([Forms]![Invoice]![GSTComboBox
YES/NO]="Yes"[Forms]![Invoice]![InvoiceCost]/(1.1),"")
But i keep getting a error.

Anyone here have any idea????

Thanks in advance [ Edit Your Post ]

As posted, you are missing a comma after
[Forms]![Invoice]![GSTComboBox YES/NO]="Yes"

Also I would return Null instead of a zero-length string (ZLS). If you return
a ZLS, then the IIf will typecast the result of the calculation as a string.

IIf([Forms]![Invoice]![GSTComboBox YES/NO]="Yes",
[Forms]![Invoice]![InvoiceCost]/(1.1),Null)

What error are you getting? I see potential problems, but without knowing the
error number or message, I can only guess.

1. If the combo box is based on a Yes/No data type, the "Yes" should not
have quotation marks around it. In fact -1 might work better.

2. There isn't a comma between "Yes" and [Forms].

3. A Null would probably be better that an empty string.

4. The Invoice form must remain open.

5. You might need to use the .Text or .Value property of the Yes/No field.

Hi Jerry

Thanks for you help and sorry i haven't gotten back sooner. I have change
the way i have done the sum
IIf([GST]="YES",[InvoiceCost]/(1.1)) Or IIf([GST]="No",[GSTTotal],Null)

But this is still not working. Any help would be appreciated

IIf([GST]="YES",[InvoiceCost]/1.1, IIf([GST]="No",[GSTTotal],Null))

Hi Ciggys

I have struggled myself with "Yes" and "No" with inverted commas or without.
It never worked. But then i switched on to True and False and it started
working. Just try this. You may succeed just as I did.
