reading url querystring parameter value within <xsl:param>

atosoriginal

I have a page where i am passing a parameter value through the url querystring on click of a hyperlink .Is there anyway to set this value to the xsl param defined within a page?

For e.g.

$PAGE_LINK[test.page?Page=
select="number($Page)+1"/>]
