xsl:number problem

All,

My xml looks like this:
<solution>
  <product>
    <productID>1</productId>
  </product>
  <product>
    <productID>2</productId>
  </product>
  <program>
    <product>
      <productID>3</productId>
    </product>
    <product>
      <productID>4</productId>
    </product>
  </program>
  <product>
    <productID>5</productId>
  </product>
</solution> 

I need to put each productId in a column of a spreadsheet.  I can do that using the following:
<gmr:Cell Col="1"  Row="27" ValueType="60">
      <xsl:variable name="rownumber"><xsl:number level="any" count="productId"/></xsl:variable>
      <xsl:attribute name="Row">
         <xsl:value-of select="position() + $rownumber + 2"/>
      </xsl:attribute>
       <gmr:Content>
        <xsl:apply-templates/> 
       </gmr:Content>
     </gmr:Cell>

I also need to format the cells they are in.  I tried the following.  But the startRow and endRow are same.  Only one cell is formatted -- the first one.  My question is how I can get the last number of the total number.  Please help!!!
<xsl:variable name="totalnumber"><xsl:number level="any" count="buProdId"/></xsl:variable>
        <xsl:if test="$totalnumber!=''">
        <gmr:StyleRegion startRow="26" endRow="26" startCol="0" endCol="0">
          
          <xsl:attribute name="startRow">
            <xsl:value-of select="27 + $totalnumber"/>
          </xsl:attribute> 
          <xsl:attribute name="endRow">
            <xsl:value-of select="27 + $totalnumber + $totalnumber"/>
          </xsl:attribute> 
          <gmr:Style HAlign="8" VAlign="2" WrapText="0" Orient="1" Shade="1" Indent="0" Locked="1"
                     Hidden="0" Fore="0:0:0" Back="FFFF:FFFF:FFFF" PatternColor="FFFF:FFFF:FFFF" Format="General">  
            <gmr:Font Unit="10" Bold="0" Italic="0" Underline="0" StrikeThrough="0">Times New Roman</gmr:Font>
            <gmr:StyleBorder>
              <gmr:Top Style="1"/>
              <gmr:Bottom Style="1"/>
              <gmr:Left Style="0"/>
              <gmr:Right Style="5"/>
              <gmr:Diagonal Style="0"/>
              <gmr:Rev-Diagonal Style="0"/>
            </gmr:StyleBorder>
          </gmr:Style>     
        
        </gmr:StyleRegion>
        </xsl:if>

Thanks in advance.
