If you test on these strings in the way I did it, it should work. One thing I can imagine (my little idea): You wrote the XSL-code a little bit different: <xsl:when test="..."> true </xsl:when> This means you have additional whitespaces and linebreaks at your 'true'-string, so the test will fail. You can change it to my above code: <xsl:when test="...">true</xsl:when>. Or using xsl:text: <xsl:when> <xsl:text>true</xsl:text> </xsl:when> Or when testing on $allowedItem you can use normalize-space(), which removes the whitespaces and linebreaks: <xsl:if test="normalize-space($allowedItem) = 'true'">. I don't have more ideas. Joerg XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
