Load external SWF w. Movei Clip?

I need help loading external swf’s with a Movieclip symbol.

I hade buttons, but wanted to keep them on when they where pressed. So i had to change them to Movie clips. I got this to work.

Now my action script to load the swf doesn’t work:

on (release) {
loadMovieNum (“davebio.swf”, 1);
}

I am guessing this is only for buttons? I want to load the swf into a level, how do I do that with a movieclip symbol?
