Button linking to a movieclip?

Hey all!

I’m finishing up a cool flash site, but I’ve been stuck on one last thing for about a week now. This is the first site I’ve ever really done.

There is a small image (button) that I am trying to link so that when you click it, it pops up another separate window to show the full image and more info.

The movie clip I’m trying to get to pop up is called ‘Holding’ and it’s in the Library. I understand the basic code:

on (release) {

BUT, it doesn’t work. When you click the button nothing happens. I CAN link to another existing movie clip that shows up under _root and that works. This one, however, does not show up under _root.

I’ve also tried it with:

on (release) {


on (release) {

What am I missing?
