I really need some help with something in my game

I really need some help with something in my game, I watched a tutorial on how to make a working boarded up door system, and that worked but It wasn’t very specific and was just that you walk up to a door press e on each board and they come off and then you can open the door. But I want it so that you can only take the boards off if you have a crowbar that you can collect. I have tried merging them but the main Problem is that you cant put a branch node into the back of a custom event node, and now I don’t know how to make it work. Help is Greatly Appreciated ( :

If I understand your problem correctly:
You cant put pin into the back of your custom event but you can call it.

the thing is I have tried that but for some reason it just makes it so that I cant remove the boards at all even if i have the crowbar
