I’m looking for a prototype for setting mc’s to fade in or out but I’m stuck with the code…here’s what I have so far

MovieClip.prototype.fadeIn = function fadeIn() {  
mc.onEnterFrame=function() {  
mc.\_alpha+= (targetAlpha-mc.\_alpha)/ease;  
}  
}

MovieClip.prototype.fadeOut = function fadeOut() {  
mc.onEnterFrame=function() {  
mc.\_alpha-= (targetAlpha-mc.\_alpha)/ease;  
}  
}

so far I cant get it to work…any ideas ?
