Issue with Gun Scripts

[AkaiHellerium (Clannerism)]

Hey! So I need some help with this script. The issue is whenever I initially equip a gun none of the animations load, whenever I unequip and re equip they work well, I’ve scanned a lot but cant seem to find the issue. Maybe one of you can, Thanks!

Everything else works. For example, shooting, reloading, etc. It’s specifically the animations.
