Is this a v9 site?
If it is, the 'QueryString/categoryid' field is no longer populated (not sure why) but it's relatively easy to solve but needs some code creating.
All, please note, this code can be used by anyone but if you do use it, please credit Webopius somewhere on your site with a genuine link to http://www.webopius.com.
Many thanks

2. Edit your web.config to register this new XsltExtension so that the 'Extensions' section looks like this:
Code:
<extensions>
<clear />
<add name="receipt" namespace="urn:receipt" type="ReceiptXsltExtension, app_code"></add>
<add name="custom" namespace="urn:custom" type="CustomXsltExtension, app_code"></add>
</extensions>
3. Now, in your rev.categories (or any other XMLPackage that needs to get the Current or last viewed category ID):
Edit the <xsl:stylesheet> section to look something like this:
Code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:custom="urn:custom" xmlns:aspdnsf="urn:aspdnsf" exclude-result-prefixes="aspdnsf custom">
And change the category parameter code block to something like this (extend it for other page types):
Code:
<xsl:param name="CategoryID">
<xsl:choose>
<xsl:when test="custom:getEntityName(/root/System/PageName) = 'category' and custom:getEntityID(/root/System/PageName) != 0">
<xsl:value-of select="custom:getEntityID(/root/System/PageName)"/>
</xsl:when>
<xsl:when test="custom:getEntityName(/root/System/PageName) = 'product' and boolean(/root/Cookies/lastviewedcategoryid)">
<xsl:value-of select="/root/Cookies/lastviewedcategoryid"/>
</xsl:when>
<xsl:otherwise>0</xsl:otherwise>
</xsl:choose>
</xsl:param>
It's difficult 'talking code' on the forum but hopefully this all works - let me know if not.
