Another follow up. You might want to check your code for the use of
"=" (assignment) versus "==" (equal). It looks like you should be
using "==" instead of "=" in several places.
There's some explanatory text in the User's Guide regarding the
difference in usage, as follows:
"=" (assignment) vs "==" (equality check)
There are two similar looking but completely different operators in AFL.
"=" is a variable assignment operator
"==" is an equality check operator
EXAMPLE
Incorrect code:
result = IIf( Variable = 10 , High, Low ); // WRONG
If you want to check if variable is equal to 10, you MUST use "=="
Correct code:
result = IIf( Variable == 10 , High, Low ); // CORRECT
