I have a grid off a table view that originally had a start and end columns with integer value. The
client does not want to store the start/end inputs just the result of start minus end. BUT (always
have to be a but), they still want to key it as start / end.

Is there a way to build a 4 column grid:
- Description: have a field in the table for this
- Qty Start: text box numeric input only - not saved
- Qty End: text box numberic input only - not saved
- Qty Sold: have a field in the table for this - difference from the above two

I already have a whole slew of temporary tables and would prefer not to create ANOTHER one!!!

Thanks

Pete
