Sorry Charles, I will try to elaborate some more. Here is a sample of the XML, my stylesheet code, as well as the error that I get from Antenna House when I try to render. XML TABLE <informaltable> <tgroup cols="2"> <colspec colname="col1" colwidth="1.5in"/> <colspec colname="col2" colwidth="2.0in"/> <tbody> <row> <entry colname="col1" > </entry> <entry colname="col2" > </entry> </row> </tbody> </tgroup> </informaltable> STYLESHEET <xsl:template match="informaltable"> <xsl:param name="colwidths"> <xsl:choose> <xsl:when test="contains(tgroup/colspec/@colwidth, 'in')"> <xsl:value-of select="substring-before(tgroup/colspec/@colwidth,'in')"/> </xsl:when> <xsl:otherwise>0</xsl:otherwise> </xsl:choose> </xsl:param> <xsl:param name="sum.colwidths" select="sum($colwidths)"/> <fo:block>Total Column Widths = <xsl:value-of select="$sum.columns"/> </fo:block> </xsl:template> ANTENNAHOUSE ERROR --- Format Abort --- 6145 (1801):Missing end tag.

Unfortunately, the column width attribute that exists in the XML has the inches designator included in the width value. I have set my stylesheet up so that the 'in' designator is filtered through another variable using the substring-before() function, but as soon as I attempt to use the sum() function with the first variable my stylesheet bottoms out. Any help would be greatly appreciated. <xsl:param name="colwidths"> <xsl:choose> <xsl:when test="contains(tgroup/colspec/@colwidth, 'in')"> <xsl:value-of select="substring-before(tgroup/colspec/@colwidth,'in')"/> </xsl:when> <xsl:otherwise>0</xsl:otherwise> </xsl:choose> </xsl:param> <xsl:param name="sum.colwidths" select="sum($colwidths)"/> Thanks in advance.
