Multiple Movie clips and rollovers

Hi, I need some help. I am putting together a flash file with 3 movieclips. I have three movie clips I made - one for each of the 3 big circles. When they roll over the other circles are supposed to disappear under the circle that they have their mouse on. I placed all 3 movie clips on the first scene, but when they roll over one of the circles the other circle movie clips stay there while the other one runs on the mouse over. I need the other ones to disappear. You can view what I have so far: [COLOR=#800080][/COLOR]. If you need to see my fla file I can email it to you. I don’t know if I have set the whole thing up wrong, with creating the different movie clips or what… Thanks! Stephanie
