Trying to make a giver with no duplicate items but i cant figure out why it isnt working.?

So I'm trying to make a little arena that when you walk up onto the plate it gives you a sword. The sword is stored in the lighting. The problem i'm running into is that when I equip said sword, it gives me another. This makes it so i can spam lunges in between the 2 swords and that's a problem. Any idea on how to fix it?

I think you should make a BoolValue to check if the player already has the sword when he touches the plate.
