The sort parameter "param2" should be initialized to a non-empty value. Check your stylesheet.

Hi
even after giving the default value the error pesists.
consider a tag where in i am using param2
<xsl:sort select="some expr" order="{$param2}" />
it fails to extract the proper value of param2 parameter which
i have passed it always takes the default value.
