EXPANDING & CONTRACTING MENU TABS

Author: Sony BMG Music Australia
Author Notes:
Each menu requires the following:
1. Must be a bulleted list with any ID specified in 
the <ul> tag & with class of 'pageTabs'
2. Each <li> must contain: 
<a href="link"><h2>Label</h2></a>
3. The ID of each <h2> must be the same ID as the <ul>
followed by '_tab[TABNO]' (eg. 'storeTabs_tab1')
4. Flash file must be in at the correct location
specified in the 'swfURL' var (line 26)
5. Tabs will not look display correctly if the 
relevant CSS styles are not included on the page.
