[xsl] how to get variable value outside scope

---

---

I have an application whose data resides in an Access database. The
application bascially loops through a number of categories, and for each
item ("news_post") in each category, loops through and transforms the
data into HTML. What I am trying to do is capture the value of the
"category" variable and pass it outside the current scope so I can link
to another page with more content relevant to the specific category. 

I don't know how to either declare the variable in a scope that will
achieve my purpose, or pass the value through.

Above is a link to the output and here's the code below. Any help would
be appreciated.
