Okay, have you set the int ‘PantsUpCounter’ in the game state? Also, regarding the image you supplied us with, the target for ‘PantsUpCounter’ would be applicable with the ‘As Game State’ cast to node.
Also, create your own ‘BP_GameState’ and make sure that the Game Override for your map is set to include ‘BP_GameState’ as your Game State. When you go to cast to this object, you will search for ‘BP_GameState’. You will not cast to the default ‘GameState’ unless you have set the variable there.
