Hi everyone,

I'm using a very nice jQuery content slider called Easy Slider on my site that I downloaded from Css Globe.

The script is excellent and does just what I want - except I can't make it randomise the list, it always scrolls from left to right or right to left!

I'm far from good with JavaScript, so my attempts at solving this have been feeble. Although I'm sure it must be an easy fix!

If anyone wouldn't mind taking a glance over the script to see if they can spot what I need to change to make it random it would be greatly appreciated!

I've tried contacting the original plugin developer but have had no response yet. The comments on the Easy Slider page didn't bear much fruit either unfortunately.

I've pasted the script I'm using on my site below:
