Greetings John,

I'm not sure this will help but, you can try:

let say you have a public variable "NV"//
Public nv
nv = 10

and a cursor //
create cursor ccursor (num n(9,2))
append blank
repl num with 10

From the Report Designer Assign the variable name: (under Variables:)
v1

then the [Value to store]:
nv + ccursor.num

the result displayed will be 20!

Good Luck

Sincerely,
Arthur
