Movieclips navigation problems

Hi every one.

I’m trying to discover an learn as much as possible at my own. But as most of us know, that’s not easy. (sorry fore my bad English, I’m young and reckless and also Sweedish) any way.

I’ve just learn how to preload external .swf by an tutorial I found at this site.

Insted of using regular buttons I wanted to use movie clip so that my buttons could have sliding menues with regulur button. But I cant use the button that are in the movie clip for navigation with external .swf. Why is that so. In wich way I do cant I use movie clipps to navigate. Or have I missed some kind of action script. Can some one that knows what I’m talking about help me.
