My FE tool doesnt seems to work when I press Q. Please help?

I am trying to make a lightsaber that is compatible with FE. I used 2 particle emitters and one union which is the saber. However, Everytime I press Q using User input service, Things go wrong. First time round, The saber activates but when I press Q again, the Saber goes down but the particle emitter stays up. And when I unequip the tool, The saber is still up for some reason. I tested it in both Studio and in game. Here are both the local and the server scripts: Thank you if you help.

EDIT fixed.
