Scripts overlapping/cancelling each other out?

I'm writing what should be very simple HTML CSS and Jquery code, but since I'm somewhat new to this stuff I'm still having trouble figuring it out. please help.. I'm trying to get the slideshow on this page http://vbwtest.comeze.com/index.php to be exactly the same as the sli开发者_如何学编程deshow on http://vbwpublishing.3dcartstores.com/

there are 2 problems with it though. On my vbwtest site, the button to switch images won't show up and then the obvious problem of the script not working. It used to, but then I changed something/added some jquery and it all broke. So if someone could enlighten me in what I'm doing wrong, I'd appreciate it. Thanks!

After looking at the sites code with firebug, i have noticed the arrow image wont load because it is linked incorrectly in the css file.

With regards to the script not working, the slider works fine. Even the arrow button works without the image.
