Help to send querystring to XSLT

This is my code in the products.asp file:
 
<%
Dim objXMLHTTP : SET  objXMLHTTP = Server.CreateObject("Msxml2.XMLHTTP.3.0")
Dim objOutputXMLDoc : Set objOutputXMLDoc = Server.CreateObject("MSXML.DOMDocument")
 
Dim strMethodPkg
Dim strMethodResultXML
 
Dim catID		:	catID = request("catID")
Dim Html_Strip	: Html_Strip = 1
 
 
strMethodPkg ="<?xml version=""1.0"" encoding=""utf-8""?>"
strMethodPkg = strMethodPkg &"<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">"
strMethodPkg = strMethodPkg & "<soap:Body>"
strMethodPkg = strMethodPkg & "<Product_List_Xml xmlns=""http://www.estaronline.com/webservices/"">"
strMethodPkg = strMethodPkg & "<catID>" & catID &"</catID>"
strMethodPkg = strMethodPkg & "<Html_Strip>1</Html_Strip>"
strMethodPkg = strMethodPkg & "</Product_List_Xml></soap:Body></soap:Envelope>"
 
objXMLHTTP.open "post", "http://www.champions.co.nz/shop/products2.asmx", False
 
objXMLHTTP.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
objXMLHTTP.setRequestHeader "Content-Length", Len(strMethodPkg)
 
objXMLHTTP.setRequestHeader "SOAPAction", "http://www.estaronline.com/webservices/Product_List_Xml"
 
Call objXMLHTTP.send(strMethodPkg)
 
strMethodResultXML = objXMLHTTP.responseText
 
objOutputXMLDoc.LoadXml(strMethodResultXML)
 
sXml = objOutputXMLDoc.SelectSingleNode("//Product_List_XmlResult").ChildNodes(0).xml
 
Set objXml = Server.CreateObject("Microsoft.XmlDom")
Set objXsl = Server.CreateObject("Microsoft.XmlDom")
 
objXml.LoadXml(sXml)
objXsl.Load(Server.MapPath("product.xslt"))
sProduct = objXml.transformNode(objXsl)
 
%>
 
 
Here is the product.xslt file. I tried using "<xsl:value-of select="//Quersystring/@catID"/>" but it didn't work
 
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:template match="/">
 
    <xsl:apply-templates select="iSAMS/PRODUCTS/product"/>
</xsl:template>
 
<xsl:template match="product">

    <td width="140" valign="top"><div align="center">

	<img border='0'><xsl:attribute name="src">http://www.champions.co.nz/shop/productimages/<xsl:value-of select="@ImageSmall"/></xsl:attribute></img>
