How do I make a system that changes a variable when I click a specific menu slot?

[MarioBlock]

I'm trying to make a power GUI for a god game, and my system doesn't work. It functions (or rather, is supposed to function) as follows:
PlayerEvent: Click Menu Slot
If Player Cursoritem: Item1
Set Var to 1
If Player Cursoritem: Item2
Set Var to 2
SendMessage: Var
Can someone help me make this work in some capacity?

instead of cursor item, use game value: event item
