Tabbed doc viewer + variable URL

[egg]

1) Script Title: Tab doc viewer.

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex3/tabdocviewer.htm

3) Describe problem:

How can I pass a variable into the URLs?

I'm currently opening some pages using the following:
<input type="BUTTON" value="example results" onClick="location.href='http://example.com/search/?query='+mysearch;">

I have many links/buttons using the same format - just changing the URL.com

How can i reproduce something similar using the tabbed system?

Thanks!
