ActionScript 3.0 :: Attach 2 Of The Same Movieclips At Once

s it possible to attach the same movieclip twice? for example i have two buttons and both attack Main_Page however when i test the flash and error reads "Duplicate function definition" is there a way of attaching the same movieclip more than once?

im using this code to attach the movie but when i add this code twice on two buttons duplicate error shows:

s_next.addEventListener(MouseEvent.CLICK, attachMovieclip);
function attachMovieclip(event:MouseEvent):void {
var addPage1age1 = new Page1();
addPage1.x= 0
addPage1.y= 0
addChild(addPage1);
}
