Help Please? - Flash CS3 and AS3 Issues - Gallery Scroll

Hello,
I would love it if someone could help me out with this code. I’ve created a basic basic website which I’ve done quite a bit before with working buttons, text, links, etc.
Unfortunately, I tried something new today - adding a separate flash action to one particular page. It is a scrolling gallery for my ink and leather portfolio.
The buttons work fine on the main page but once I click on the scrolling gallery link through the swf file relating to that button the buttons dissapear just on that page. The other pages work. When I try to add the buttons to that page again it brings up the 1151 code error.
What am I doing wrong?!

P.S.-Whoever can fix this I owe a 20 sq/ft oil painting to.
