Hi JD.

>>...I think my syntax telling this generated number to be displayed in bun1 is missing something, but in case i'm wrong, my types are:
1. bun1 is a combo w/ numeric value (no decimals) <<

Do you have BoundTo set to true for Bun1 and Len1? If you want the combo to take its value from the list instead of the listIndex when its value is numeric, you must set BoundTo = .T.

>> 2. lncol2value1 is a variable w/ numeric value (example: .667)
3. lncol3value1 is a variable w/ numeric value (no decimals) <<

Where do you have the variables defined? They go out of scope when the method in which you define them ends.

Also, if your calculated value is not in the combo box's list, you cannot set the combo box's value to it.
