help me please i dont get it

i created a script for a jet for my game The HOUR and this is wat i got and when i turn on the game...all the keys are backwards and the plane stays facing strait. here is my script

static var gameover = 0; var crashforce = 0; static var rotationx = 0; static var airplaneangley : float = 0.0; static var rotationy : float = 0.0; static var rotationz : float = 0.0; var positionx : float = 0.0; static var positiony : float = 0.0; var positionz : float = 0.0;
