Hi _tina_
I am new at this forum. Please correct me if i am doing something wrong.
Sorry for my english.

On the slider page in the examples. View the source of the page. At the top there are some javascripts you have to include in your document.
Just download the yahoo yui library (2006).
You can find these scripts in the library build files. Always put yahoo.js before all other javascripts.
I think that the slider uses pixels to count. So that would be a problem.
I think you have to use whole numbers.
Correct me if i am wrong.
You can change the range and tickSize in the javascript. Just change these values to what you like.
Dont forget to fit the css to your needs.
#demo_bg has a width of 310px.
Just set the right width to what you need.
You can create your own images or copy them from the yui library.
