Dynamicaly loading SWF problem

programming flash
1

Okay , so I have a nav bar, right underneath is an empty MC called: bottomloader

In on button I have the following code;

on (release){
    _root.bottomloader.loadMovie ("bottommain.swf")
}

When I click the button it loads ONLY the text of the external MC, nothing else, no shapes or graphics or nothing, just text! And only the main body text no even the titles!

thanks guys!
