An Obvious Problem?

programming

I know this is obvious but… I can’t figure it out!
Okay, these arms look at the mouse. When he looks behind him, it should flip him over…


onEnterFrame = function(){
    if(main._rotation <= 180){
        main._xscale =+ 100;
    }
    if(main._rotation >= 180){
       main._xscale =- 100;
    }
}

If you don’t understand… play StickManSam. http://www.crazymonkeygames.com/Stickman-Sam-3.html
Sort of like that… Help please?
