Hi Dario,
i know u aren't html expert (maybe), but i only going to http://app.lightstreamer.com/GridDemo and save as *.html file, just modified js script code (didn't modified html code).

Here my modified --> http://www.gls.com.vn:8080/priceonline/test2.htm , but it didn't show slider bar. I don't know why in HTML code that declares the slider is grayed in Firebug.

I hate to bother u but i'm a newbie in developer. I apologize about this.

Here my error, when you first page load.
