Im back!
Ive got a MC that im tryin to change the alpha value of. it has 25 frames in it, and the first frame says
onEnterFrame=function()
{
if(_global.abc=true){
gotoAndPlay(2);
}else{
stop();
}
}
for this whole thing, assume the abc variable is true.
the second frame says this.
onEnterFrame=function()
{
if(_global.abc==true){
this._xscale+=12;
this._yscale+=12;
this._y+=3;
this._alpha+=4;
}else{
gotoAndStop(2);
}
}
this is followed by 25 frames where the scale and y value change, but the alpha value stays at 0. Ive tried google, but every solution says exactly what I am doing. Can anyone see where Im messing up?

have you tried capitalising 'Alpha', sometimes things like that are all that wrong. Apart from that the script should run fine.

capitalise or add some dots somewhere... that always works...
