Parent/root Functions, Importing The "children"?

I have an swf file, MyRoundButtons, which is a set of radio buttons I built (not components). It works fine, but if I import it into a parent it won't work anymore. I have to write a script to load it into a movieclip, (which I hate, because I'll have a several different swfs to assemble on my final stage. I really want to see them all on the stage together, not just at runtime.)Even when I load it into a clip and the buttons work, however, it doesn't seem to have a separate timeline when double-clicked ,and: I can't make the imported buttons control the timeline of the parent. I defined a test function:

Code: Select allfunction goToNirvana() {gotoAndPlay("nirvana")};

Frame "nirvana," in th parent, has a Trace instruction in it.goToNirvana works on its own in the parent. Now to call the function from within the child:

Code: Select alltv_btn.onPress = function(){
gotoAndPlay("TV");
// That last part triggers the button's down state and sound in the child timeline, in frame "TV."

[code]....

Whether I define that function in the child, the parent, or both, the instruction won't work. Now, I'd prefer not to do the loadMovie thing at all if I can avoid it, I'd rather have fully rendered button clips onstage at authoring for me to arrange and move about, with fully independent timelines right there. But you see what I'm trying to do. I just can't get it done.
