First person arm visibility script works only once?

Hey, so I have a localscript that I have put in my PlayerGui, and when I spawn in, the script works perfectly but when I reset / respawn, the script does not function anymore and there is no available output given from the script.

Would be appreciated if anybody could help. Thanks
