Hi, I have a grid on my form and, in the BeforeRowColChange event I have the following: IF INLIST(nColIndex, 2, 4) REPLACE Total WITH Item * Cost ENDIF The strange thing is that, if I am trying to exit column 2 of the grid, the code works fine. If I'm exiting column 4, it doesn't do squat. If I tab through the rest of the fields so that I'm exiting column 2 again, it works fine again. (I know that I shouldn't have a field in a table that can be calculated from two other fields in the table but there are reasons why it has to be that way for now.) One thought I had is that nColIndex also counts the record marker (which is displayed) and deleted record (which is _not_ displayed) columns and that what I'm seeing is it working for column 4 with column 2 being hidden. IOW, I should be looking at 4 and 6 instead of 2 and 4. However, when I tested this idea, it didn't work either. Any idea what I'm doing wrong? Gary J. Sibio
