This script worked before but, now it doesn't

Ok so here’s the scenario there is this sans script thingy I was gonna make for a game. So I started modding it so I could use it for a game. Then I quit for a bit cause school started then when I came back to it I was running the script and the error on the image appeared


Now, I’ve tested this script before and it worked perfectly ok. But, here’s the weird part
I go to an old script with basically the same exact lines of code but there are different attacks. If there was an error in one of the attacks that wouldn’t prevent the script from running. I run that script and it works perfectly. This was so confusing, I’m not gonna send the entire script cause it’s over 1,000 lines and I don’t know where the error is, the original script doesn’t work as well when it did before. If you want look through it for errors here’s the link to the script: Sans leak - 🧌 - Roblox yes you might say I stole the script but I’m planning to add a lot more modifications. Please help I’m kind of new to scripting if I could do this myself I would.

On the line where the error occurs, you seemed to have used the “ character instead of ". Try replacing all fancy quotations as Roblox won’t be able to understand it.

I tried looking for fancy quotes but, that didn’t work there were none in the script
(sorry for late response I fell asleep)

Wait no I’m so stupid it was not in the script it was in the require I’m so stupid, thanks for your help
