The for loop initial value is only evaluated first time into the loop, and you have to decrement through it because the forms array collapses itself down as forms go away. The loop counter was 2 in the post mortem dump that got delivered in my morning email.

Sometimes I'll get stupid errors like Columns is not an object in a builder that's working on a currently instantiated grid, cancel and run it again and it works just fine. Ah VFP you gotta love it. *g*
