Question about clearing a MovieClip - unloadMovie()?

1

I have an XML photo album that I’m building which displays thumbnails based on a combBox selection. The thumbnails are generated via createEmptyMovieClip within a movieClip with an instance called thumbnail_mc.

My problem is… once the thumbnails populate and another selection is made from the comboBox the current thumbnails need to be removed before the new once are populated.

I’ve tried calling thumbnail_mc.unloadMovie() to clear the movieClip before calling the function to populate the new thumbnails. But it doesn’t seem to work. The new thumbs don’t appear.

My script looks like this on comboBox selection:

[COLOR=RoyalBlue]*//clear thumbnail container movie clip
thumbnail_mc.unloadMovie()

//build an array containing all thumbs for selected album
thumbnails = [];

imagesTotal = selectedAlbum.childNodes.length;
for (i = 0; i < imagesTotal; i++) {
	thumbnails*	* = selectedAlbum.childNodes.attributes.thumb;

            // generate image for each thumbnail via function
            thumbnails_fn(i);
}

}* [/COLOR]

Any help or suggestions would be greatly appreciated!
