My application, to make matters simple, has 4 elements:

Program:
Cost:
Amount Paid:
Balance Due:

In the programming of this application I have an initial value for the cost, let's say $450.00. My client sends in a payment of $400.00, his Balance Due is $50.00. No problem so far. If I give a client a discount of say 50%, his Cost would be $225.00. When I exit the application all is saved. However if I go back into the same record to change something the cost reverts to the initial value of $450.00. What programming is necessary to change it so that the cost maintains the value I choose instead of the "initial programmed value"??

Thank you Erika......but where and exactly how do I install the @IsBlank and/or @IsNew programming functions?

Hi Erika,
In my application the cost is the actual "program" ("Father-Son";"Golf";"Tennis Plus"; or "Ice Hockey"
It is in the program element: Program:: On element exit

if program:= "Father-Son" then total amount due:=500.00
Else If program:="Golf" then total amount due:=450.00
Else If program:="Tennis Plus" then total amount due:=450.00
Else If program:="Ice Hockey" then total amount due:=450.00

Hi Erika,
Thanks much! This should work.
Now, where do I install this bit of programming:
----On Element Entry?
----On Element Exit?
----On Form Change?
----On Element Change?
----On Form Entry?
----On Form Exit?
----On Element Immediate Change?

I have yet to understand the differences, my bad!

Peter

Thank you Erika!!
