Contractible Headers Script: parameters in the URL

[Drieske1982]

Hi,
I'm using the "Contractible Headers Script" i've found on http://www.dynamicdrive.com/dynamicindex1/navigate2.htm. It's a great script, but i miss something...

I would like to like to certain "expandcontents" from another page. Let me give you an example.
I use this script on page1.html. But i want to put a link on page2.html to page1.html with a certain textblock expanded.

I think it's possible to do this with a parameter. For example, by linking to "http://.../page1.html?expandcontent=sc1".

But my knowlegde of javascript is very limited. Does anyone know how i can program this?

Thanks!
