Hi!  
I have this code to load an external swf and changing it’s \_alpha.  
Problem is that the function doesn’t works on the clip.  
mx-guest2004  
[AS]  
\_root.createEmptyMovieClip(“butt”,21);  
loadMovie(“photobutton.swf”, “butt”);  
setProperty(“butt”, \_alpha, 0);  
function reAlpha(clip, targ, speed) {  
if (clip.\_alpha\<targ) {  
clip.\_alpha += speed;  
} else {  
clearInterval(reAlphaInt);  
}  
}  
reAlphaInt = setInterval(reAlpha, 20, butt, 100, 5);  
[/AS]
