_alpha setting disappear after gotoAndPlay(1)?

programming flash
1

Hi,

On frame 1 i have


var mc_top:MovieClip;
mc_top._alpha = 68;

And after our hero dies i have this code in frame labeled “die”


gotoAndPlay(1);

also tried


gotoAndStop(1);

But now the _alpha setting isn’t shown???

Any ideas?
