364810 javascript range slider

I have a greasemonkey script that I use with youtube, however I would like to add a javascript range slider to it. However I am having trouble getting any of the javascript libraries that have range sliders to work in a greasemonkey userscript. examples of javascript libs with range/dual sliders; [login to view URL] [login to view URL] jquery have one as well; [login to view URL] greasemonkey is; [login to view URL] I am on firefox 3.5 on linux x86_64 running greasemonkey 0.8.2009xxxxx so i want a greasemonkey userscript that simply shows a range slider on the screen, or added to the bottom of the page or whatever.
