>>>Sorry it took a while to respond. The info I gave you was directly out of VFP's help. I tried what you are doing and got the same error. I am not 100% sure what the problem is but I'm almost positive it's the IIF. Try going to the DynamicBackColor of one of your grid columns and go into the formula builder (...). Play around with your syntax from above until it tells you it's valid and then try the revised syntax in the SetAll statement.

All IIF, it should be character.
