Num in Solve App. ISCHECK()

[toshk]

In Solve App when 2 or more equations are involved; Num has a Checkbox against the variables
Is there a way to find what is checked for that variables? ISCHECK()?

if not.....
I wrote a dynamic input function to find what variable is check for an App. For which INPUT function fails to execute. Any HELP?
my function input consist of: checkbox; value1 box, value2 box, checkbox.
Similar to Solve App with 2 or more equations with total of 7 or more variables.

Code:
