I need help with Rabbit Racer

To be honest, this isn't a great place to post questions on programs that you're working on. Khan Academy has a way for you to do that with out even having to leave the tab.

To ask for help on a program, scroll down until you see the section entitled "Help Requests" and post your question there. Someone will see it on the recent help requests list, and it should be answered in a few days at most.
