Sliding website

Hello!

I have been following this tutorial

http://www.kirupa.com/developer/flash8/slidingMenu.htm

to design a sliding website. I have designed each section(about, portfolio, contact etc)
of the website as a movie clip. All the movie clips were then placed next to eachother in a row. Everytime you click a button the site is supposed to scroll
to the next movie clip. This has been working fine until I changed the size of the content. The current content(each content movie clip) is now 1000x600. The problem now is that when you click a button, it doesn’t scroll far enough.

I have been looking through the code but as far as I can tell the code is written in a way that the size of the content doesn’t matter. I haven’t changed anything in the code from the tutorial.

The .fla was unfortunately too large to attach.

Would be very thankful for help!

Cheers
