Hi. Need some help.

I have this code. It works fine when i press a button.  
[AS]

if (\_root.mc.\_alpha == 100) {  
this.onEnterFrame = function() {  
speed = 50;  
alpha = 0;  
a = alpha - \_root.mc.\_alpha  
\_root.mc.\_alpha += a/speed;

}

[/AS]

What I need?  
I need to know how can I trace the \_alpha value of the mc and when the value is 0 a movie clip is loading in the same mc.

Thanks in advance.
