javascript xsl parameter
You can test if the parameter is getting passed by displaying it in
your output...

<xsl:template match="rwsdomesticportfolio/partner">
<xsl:value-of select="$partnername" />

but I believe your problem is that you don't need the single quotes here
<xsl:if test="varpage='$partnername'">

this should work
<xsl:if test="varpage=$partnername">
