Background Load Script Help Please

Hi! OK, Im reposting this, but i did some work on it and figured out a possible actionscript function to use for what id like to do. But once other backgrounds are involved in the main swf, only the original swf background wants to stay, so im hoping someone can help!

Alrighty, this is something im working on:

This first background that loads (the photo of the lady), is also supposed to be the background for when you click on the news button at the bottom of the main swf. But when i first had that set, if you clicked on the news button, it would basically reload the background, and i was wanting to figure out how to get it to not reload it if it was already loaded. I thought i figured it out from a Kirupa tutorial, but once i added in another background for the bio button, it doesnt want to change backgrounds now!

My fla is here: http://www.meatloaf-multimedia.com/test/site1.fla

I know it has something to do with the code ive got inside the movieclip of buttons which is:

news.onRollover = function() {
if (_root.backgrounds != “background1.swf”) {
_root.backgrounds = “background1.swf”;
}
}
bio.onRollover = function() {
if (_root.backgrounds != “background2.swf”) {
_root.backgrounds = “background2.swf”;
}
};

If i take this code out, the different backgrounds load, but then im back to the drawing board of trying to get the backgrounds not to reload themselves if theyre already loaded, when someone clicks on the corresponding button, etc. Any ideas would be GREATLY appreciated!! Thanks!!
