I have a very simple grid that is acting very funny. (not <g>)
Columns 1-4 are disabled. Column 5 is numeric entry with a very simple division calculation in the valid.

Here's what's happening. I enter a value in column 5, that value is replaced by the calculation in the valid (correct)...I go down to row 2 and the result of my formula from row 1 shows up in column 4 (read only) of row 2.

Baffled, I remain. Randy
