Loading javascript files - prototip

[guls_guys]

Hi guys

i am trying to display prototip2 on a link in header. i have followed the instruction form this website
http://www.nickstakenburg.com/projects/prototip2/

if i implement these incstruction in a html page prototip works fine with no errors but when i try to access it in php it gives errors.
i have found these errors with firebug which are

1-Object.extend is not a function

2-Tip is not a constructor
[Break on this error] new Tip('bag', 'this is a test tip');

i would like to request any guru of zencart to implement prototip2 in zencart or atleat guide me in right direction.

for loading the javascript file i followed these instructions

http://www.zen-cart.com/wiki/index.p...s_-_Javascript

i have followed the instructions and to check if the files were loaded correctly i added a small function which alerts if called. then i called this fucntion in tpl_header and index pages, this fucntion was successfully executed. so this means that files are loaded perfectly in the zencart. also to double check, i viewed the page source and both the script files where included in the head section of the page.

now any one who want to get me out of misery plzzzz help me
