@KingCobra. Awesome! Thanks for responding and sharing the result with everyone. Usually, most of the javascript errors stems from jQuery conflicting with Mootools (especially the older versions of jQuery).
Mootools is really a mature and good Javascript framework. I first learned jQuery, thinking it would be easy, but coming from a programming/Computer Science background, when I used Mootools, I felt more at home. Mootools can do everything jQuery can do, and it would be good if developers stuck with Mootools, since it is the the javascript framework that Joomla supports natively. That is why I changed all my jQuery code to Mootools.
