I could attach the excel file so here is a image of it.


Beside the price 139.95 is a blank cell (E8, E11 and E15).
When a number is entered into this blank cell E8 it needs to be able to
change F9 & G9 and F10 & G10. Increase the F column and decrease
the G column.

Next is the price 79.95 and a blank cell beside it, E9.
When a number is entered into this blank cell E9 it needs to be able to
change F9 and G9. Increase the F column and decrease the G column.

Thanks, Mike
