Problem with loading

I am making a really complex flash site and i have some problems with the load command.

This is what i am doing.
I have a main flash file (index.swf) which loads a different flash file (products.swf) and the products.swf loads a different flash file (item1.swf).

Now index.swf loads products fine. and products can load item1.swf fine (not from index.swf).

However, when i open index.swf, then load products.swf i can’t load items1.swf.

How do you solve this problem?

I used this code or all of them:
on (release) {
_root.contents.loadMovie(“products.swf”);
}

on (release) {
_root.contents.loadMovie(“item1.swf”);
}
