Trying to archieve a delay for each movieclip

1

Hi there.

I hope someone can help me grasping the concept of delay.

My problem is the next.
I am making a kind of gallery using an xml file.

Now ,when i attach a movieclip for each generated item i have into my main mc,
“this movieclip is kind of a holder for an image with some information and a button”
They come up all at once ,
i would like them so show up ,for example 500 msec after each one.

so i thought i could accomplish this with setInterval ,
but with no luck for now

The code that attaches it is:

 
for (var g=offset; g < fin ; g++) {
var BoxHolder = moviecl.attachMovie("new_item","item"+my_counter, my_counter);

I tried to change this to:

 
myfunction(mc,attachmc,attachId,my_counter)
{
return BoxHolder = mc.attachMovie("attachmc","attachId"+my_counter, my_counter);
}
 
for (var g=offset; g < fin ; g++) {
setinterval(myfunction,500,"myID"+my_counter);
var Box =myfunction(moviecl,new_item,item,my_counter);
clearInterval("myID"+my_counter);

If anyone could help me or tell me how to accomplish this , would be greatly appreciated.

If i am not clear to you ,please let me know to see if i can explain it better.

Thanks in advance

Luck
