Combo is null


W

Walter

I have 3 unbound combos on a form. Combo2's rowsource uses combo1's value as
criteria. Combo1's AfterUpdate Event requeries combo2. Upon making a
selection in combo1, there are no choices in combo2. Also after update of
combo1, if Combo1 = "this value" then do this. In testing with a code break
there, combo1 is null even though "this value" is selected.
Combo1 Rowsource:
SELECT DISTINCT MyTable.Field1
FROM MyTable
WHERE (((MyTable.Field3)=False));

Combo2 Rowsource:
SELECT DISTINCT MyTable.Field2 FROM MyTable WHERE
(((MyTable.Field1)=[me].[MyCombo1]) AND ((MyTable.Field3)=False));

Column count:1
Bound Column:1
RowSource Type:table/query
LimitToList:Yes
ColumnWidth:1"

Is that SQL statement "in" your form, or is it the query's SQL?

By the way, what data type is MyTable.Field1? Based on your second SQL, it
would have to be a number data type, since you didn't use any delimiters
around the [me].[MyCombo1] ...

I probably would have used Forms!MyForm!MyCombo1 to specify the value in
MyCombo1 ...

Good luck!

The sql is copied from the combo's property sheet. The data type is text. I
suspected this was the issue however I've been unable to get the delimiters
right. What is the benefit to using the forms!MyForm!MyCombo! ?

The Forms!MyForm!MyCombo reference corrected the situation without any
delimiters.

Text is delimited with quotes.

"Me." refers to the active form (or report).

"Forms!MyForm!MyCombo" explicitly points at a specific control on a form.
