Background layer not dissapearing

I am trying to use one of the layers on my stage which is just a black rectangle for a background in another swf file so that when you press on the button which brings you to my other swf file the rectangle acts as a background. I gave the layer which has the rectangle in it an frame label name. Im not sure what the code is, I want the rectangle to be invisible on my stage and have it appear when you press the button to go to my file which is called one.swf. I thought i could make the background image to = false and then on an onpress make it = true so when you open one.swf it will pop up. Right now its just taking over my whole stage…well im sure theres other ways but hopefully someone can help, i am not in a rush or anything so thanks a lot for any help. i also have a few more problems so if theres any way i could upload my file for someone to take a look let me know too… ok thanks…
