loadMovie(scroll.fla)into main.fla-not scrolling

Hello. I have created a .fla file containing a scroll window (not scrollPane, homemade), scroll.fla. It scrolls fine as an independent .swf file but when I load it into my main movie, main.fla., it will not scroll.
I have changed the path in the scroll.fla to incorporate the path in main.fla but that didn’t work either.
Any ideas are greatly appreciated.
Thank you and best regards…
