Getting Variables from Option Men --CORRECTION

[Mark Schonewille]

Charles,

Why variables?

on mouseUp
   if the label of btn 1 is a number and ¬
   the label of btn 2 is a number then
     put the label of btn 2 - the label of btn 1 into x
     -- do something with x
   end if
end mouseUp

No need for a script in the option menu buttons.

Best,

Mark
