Problem turning left after build

Been following tornado twins' unity tutorial, and added a few lines of script of my own. When I play the game in the engine, it turns left just fine, but after i do a build and run, left turn no longer works. everything else works just fine. i can post the script up if you need me to. thanks for tacking the time to help

yea, i must have just hit the input window and messed with something. all fixed now

Hello friend can you tell me how to solve it is that I had the same error but I do not know how to solve it I would appreciate your answer
