Blueprint matchbox required to spawn fire in furnace working 50/50

thanks for the feedback guys, i tried changing the ‘E’ key on the second event but no luck with that :s, iv also played around with the overlapping actor etc as you said Fen but I dont think im doing it right at all, im not too sure how to go about doing that part of the blueprints as of yet as iv only been using UE for a few weeks with doing mostly building so im new to the blueprints/ mechanics side, and ill try what you said , where would i place the IsValid in my blueprint?
EDIT: I think the ‘IsValid’ worked, will keep you updated
