JQuery slider not showing in IE and Chrome, but showing on FF

I downloaded a jQuery slider from dynamicdrive.com and embeded it into my site. It has the ability to play, pause, forward and previous scroll the pictures. It was working fine before on all three browsers, but it wasn't showing the icons for controlling the slider.

So I declared a variable in the head, and assigned them the path of each picture. Then, I called those variables instead of pictures. Now it is showing on Firefox, but not on any other browser. The sl开发者_开发百科ider is on left side after the login form on my site.

you can bet for jQuery and Prototype conflict as magento uses Prototype and they both bind to $ as their method name
