Hello friends,  
I’m quite new in flash and I’m finding it very stressful to write as codes.  
I’ve written a flash interface class for loading movies, but I’m stuck with callback and eval functions, so If anyone can help me, I’d be much appreciated.

Basically, I’m calling a class member function like this:

**this.call** ({  
name : “window”,  
pos : [x,y,w,h],  
target : \_root.frame,  
\*\* onComplete: function(p1,p2){  
trace(‘hello’ + p1);  
}  
\*\*});

… somewhere in timeline when movie loaded…

mcl.onLoadComplete=function(mc){  
eval (caller. **onComplete** )  
}

I just want to ask if I can evaluate the onComplete function in that way?  
Thank you in advance for any comments,  
Alex
