I apologize in advance if my question has been answered elsewhere. I did a forum search but didn't find anything on it, but if it has been answered already feel free to point me in the right direction.
I am wondering, is there a difference between a global variable and an instance variable? I know that globals can be used/seen throughout event sheets and instance ones cant, but is there a reason to use one over another? Or perhaps something else I'm overlooking? Thank you,
