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]

Change the alpha **after** the swf is fully loaded;)

Thanks Scotty, the button works now. But I have another problem with the same code inside the button.  
You know, I think there is something with the path.  
I have a button loaded into the main movie (OK). This button loads an external swf into the main movie. I want to increase this external swf’s \_alpha by this code.  
I use this code:  
[AS]  
on (release) {  
\_root.createEmptyMovieClip(“album”, 1);  
\_root.album.loadMovie(“mymovie.swf”);  
setProperty(“album”, \_alpha, 0);  
function reAlpha(clip, targ, speed) {  
if (clip.\_alpha\<targ) {  
\_parent.clip.\_alpha += speed;  
} else {  
clearInterval(reAlphaInt);  
}  
}  
setInterval(reAlpha, 20, album, 100, 5);  
}  
[/AS]
