>>I have a grid where 2 of the columns contain comboboxes. The first column contains a single "type" combo, which has 3 hardcoded choices. The 2nd column contains 3 different combos that match the selected type of the first column. I was hoping to use a DynamicCurrentControl command to set the correct combo based on the value in the first column, but no joy. The form's activate method does correctly set the dynamiccurrentcontrol for a different column (which shows a commandbutton), but i'm missing something w/ the other column that has 3 combos in it. It doesnt error out, but i am not getting the result i expected.

>>When the form displays, regardless of the value in the "type" combo (1st column), the "currentcontrol" combo in the 2nd column is not predicated on the field referenced in the "dynamicacurrentcontrol" command used in the form's activate. Wondering if i should bail on the SQL statements as the row source and go w/ cursors.

Cetin - thanks for the reply. I added the parens around the IIF. Still has issues though. The idea w/ the 3 combos in the one column was to dynamically (via currentcontrol) point to one of them based on the selected value in the other column. So:
Column1       Column2
Type          Choices    
====          =======
Ceiling       Tiles
Ceiling       Panelling
Floor         Asphalt
Floor         Concrete
Floor         Tile
Floor         Marble
Wall          Drywall
Wall          Plaster
In the INIT, i am creating 3 cursors based on what matches with Ceiling, floor, and wall. Those cursors are the recordsources for the combos in col2.
