My 173 Script Wont Work When Published, It just doesn't move, when i look away, can anybody help?

the script i have, or when i publish it, doesn't work, like lets say i publish it as a game, the script doesnt work what i want it to do is, move when i'm not looking, it does that if i dont publish it, but when i publish it it just doesn't move, it does nothing
