Attach 2 of the same movieclips at once

Question

is 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 addPage1:Page1 = new Page1();
addPage1.x= 0   
addPage1.y= 0
addChild(addPage1);
thanks for any help

Answer 1

there are 7 buttons in total on the main page.
Under the contents menu:
Children Day - 1 instance name = s_gotoPage1
Yellow color day - 2 instance name =  s_gotoPage2
Summer Festival - 3 instance name = s_gotoPage3
TWP Daily - 4 instance name = s_gotoPage4
The next page button (bottom right) instance name = s_next
the two red buttons up top link to page 1 and page 3
the page 1 button has instance name: s_gotoPage1a
the page 3 button has instance name: s_gotoPage3a
There are a total of 5 pages
The class name for these pages are as follows:
Page0 (main page)
Page1
Page2
Page3
Page4
i can also provide the fla source if needed
