Score in game causes error code, even though same code for score works in previous level/lessons

**Link to the project or level:** [https://studio.code.org/projects/gamelab/xJdz4IZggqtm0Zu9wFoYHftMhulWZhNw8upHZa63I9s](https://studio.code.org/projects/gamelab/xJdz4IZggqtm0Zu9wFoYHftMhulWZhNw8upHZa63I9s)  
**What I expect to happen:** score shows during game play  
_What actually happens:_\* ERROR: Line: 12: TypeError: Cannot read property ‘toString’ of undefined  
**What I’ve (& two other students) tried:** copy/paste code from working score game, build code again, switching browsers, logoff/login

Lines 5 & 39 both try to declare the variable “score”. Try removing the var block from line 39 and only having it say “score=score+1” (without the “var”).

That should fix the error!

Best of luck!

Line 39: score is already defined

You don’t want to define a variable twice, because the code won’t know which variable to use, thus the error. if you remove the var on line 39, it should work.
