My script gives me an error message whenever I end the script?

Well, you needed some more "ends" and closed ends for the functions.... I think there's a ton of redundancy here and maybe this code should be reorganized a bit.. You're setting up character added events 3 times.... all nested within a player added event... This will at least get your script running without an error, but not sure if it works, otherwise... Notice my comments to help figure out the puzzle of what was wrong.. and the formatting...
