Unloading external MCs without buttons

i have seen a few places here in the forum about how to unload external movie clips with the press of a button.

i need to dump a loaded external movie clip without the press of a button.

i thinking that this is a last frame action of the external movie clip.

if i use
unloadMovie (“name of external swf that was loaded”)

  • my cntl-enter swf just goes blank when the movie is done playing (action on the last frame)

so = to explain -
main.fla is main flash document.

button in mc calls to load “externalSWF1.swf” . that works fine

but when “externalSWF1.swf” is done playing, i want my main.fla to go back to normal - with no button press

i have “externalSWF1.swf” loading into blank movie clip holder called “logoHolder_mc” which rests on stage and main timeline of main.fla

if i can control other elements on the _root time line with a frame action on the last frame of my “externalSWF1.swf” - i should be able to do this as well.

i have tried:
_root.gotoAndPlay (1);
or
_root.unloadMovie (“externalSWF1.swf”);
or
_root.loadMovie (“logoHolder_mc”);
or
_root.logoHolder_mc.play();
or
_root.logoHolder_mc.attachMovie(“logoHolder_mc”, 0);

none of these work.

but
_root.myScrollpane._alpha = “100”; works to control the alpha of a scroll pane instance sitting in the same place as my logoHolder_mc.

thanks…
