How/when to Requery

B

Bob Richardson

On a datasheet view of a form I have Start_Time in column 1 and Classes
available in col. 2.

Col. 1, named "ST", gets filled from a lookup table. (e.g. 9:30, 10:15,
lunch, etc.)

Col 2, named "Class", is also filled from a lookup table, based upon the
classes available at the starting time shown in col 1.

My table lookups work correctly for the initial row I click when I first
enter the form. In other words, if I click the Class column in the 2nd row
of the datasheet, the drop-down list only shows classes available at the ST
on the left. Good! If I next click Class on a different row, the drop-down
list still shows classes available at the ST indicated on the initial row I
click. Whatever row I click first, when I enter the form, that's the list of
Classes that populate my drop-down list of classes, for ALL rows.

I'm guessing that I need to Requery something, sometime. But what and when?
I tried using ST.Requery in the On_Exit event of ST, to no avail.
