Adding Javascript to pre-existing Javascript Page

[nigelwong]

Hello,

I currently want to add some AJAX to a page that already has javascript. This AJAX to be specific: http://www.lissaexplains.com/forum/showthread.php?t=47016

That works perfectly fine by itself. However when i add it to a site which already has some javascript, it doesnt work. Is there a special line or something required to add additional javascript??

Thankyou~
