Sliding Menu - Buttons problem

Hi all, thanks in advance for looking at this thread.

I have adapted the sliding menu tutorial and am having a problem placing the buttons on different frames so only one is visible at a time. When applying basic actions to the button itself calling a different frame the frame will move but the contentHold movie won’t slide.

I have been working on this for days and its really starting to get annoying!! Any input would be very welcome.

My working files are here http://gd2.co.uk/downloads/WHY.zip.

Cheers
Pete
