I think I'm being dense, this should be easy, but it is not working the way I think it should. I have a grid, with a column bound to a field in a table, the field is called "threshold". I issue the following in the init of the form to highlight rows for a specific threshold, but it does not work. What am I missing? In the table there a many records where that criteria would be true.

ThisForm.grdInv.SetAll("DynamicBackColor","IIF(threshold<1000,RGB(255,255,0),RGB(255,255,255)","Column")
