Don’t know what you are doing wrong. THis took me 30 secs to create.
But, to the left of your “Cast to node” is where you INPUT into object “Get player character” OR “Get player pawn” OR “Get player controller”. Only one of them should/can be input at a time.
In your output you left click and DRAG off the blue “As charnew” pin. Now the menu will pop up, and in this you can type “Get battlestance” and it should pop up.
This menu is different than the one you receive when you just right click somewhere in the screen, as this one picks up on relevant info from the item you dragged a pin off.
This should work. (I get a compilation error as it is not a player character in my game.) And ofc. remember to compile
