Moved the "CP = SetPlayerCheckpoint etc." to OnPlayerSpawn, and added the missing "speed" parameter of the MoveObject function. Should at least get rid of the warnings and errors. Won't get rid of this: symbol is assigned a value that is never used: "CP", but don't worry about that for now, your script will run alright with this warning.
