user.js script error

Hello, all in need of serious help.  All of a sudden when I preview my file that runs javascript that has multiple javascript that runs on different slides.  I am getting an unexpected token "}". and is says user.js.4090.  Can anyone tell me where I can fix this?  I am not sure where to go since this is in my preview.  I understand the error I just don't know where to go to fix it.

I have attached a screenshot to show the error.  Also, this shows up even before I run any of my scripts.
