Animation doesn't play on trigger

So I have a game Its gonna be like one piece, from what I have seen 2 other people have made posts about this and to no avail nothing worked, so if your about to post “did you post it to your game or did you do this” just remake the script the way it should work, test it, it works? good send it.

heres the isolated place file:

Test.rbxl (72.6 KB)

make your own animation and put it in, test if it works, hope it does, if you can send back your own test file when it works
