I have been Googling and searching all over this forum for what I think is a fairly simple answer.  How can I test a checkbox in XSL?  I generated the XSLT script and can test for blank values on text:

      <xsl:if test="string-length(udt:First_x0020_textbox_x0020_here) > 0">
        <tr>
            <td>First Textbox</td>
            <td>
                <xsl:value-of select="udt:First_x0020_textbox_x0020_here" disable-output-escaping="yes" />
            </td>
        </tr>
      </xsl:if>

So that keeps the textbox from displaying on the email, but how to do that with a checkbox?

Many Thanks.
