Sliding Menus tutorial

I have completed the tutorial Sliding Menus from the Kirupa site.
http://www.kirupa.com/developer/flash5/slidingmenu.htm

I have adapted it for my own website, but can’t quite perfect it the way I want it. It basically works OK.

If you take a look at the link, it shows what I have created:

http://www.users.waitrose.com/~johnhathway/flash_problem.html

A) Shows the .swf file.
B) Shows a screen image of the .fla file.

If you look at the scroller buttons at the bottom on each, you will see one button missing on far right and one has been elongated on the far left.

I’m not sure why this is. Can anyone help please?
