Code is broken, I cannot fix it

I was borrowing some code to stop my animations from teleporting all over the place, and it seems that the first line of code has broke, and I can’t do very much to fix it. I haven’t saved my project and I’m not sure how to fix the issue because I’m new to coding.

On the first line, you need to remove the excessive amount of 'w’s (the keyword should just be enum).
But it also seems that you have a dangling backtick on line 139. (perhaps you forgot to close it?)
