Expected Identifier error

[Badstormer]

I have searched for hours on this forum and fixed every error I could find in this script, yet a persistent 'expected identifier' error continues to crash the game every time the third map in the story is loaded. This began happening after I implemented a 'venom' mechanic which takes effect after getting bit by a spider - it is a bit crude, but it will work for now.
