I have a one row and one of the columns has a list of data. Say I have a row, the 3rd column has 0 or more rows. `<xsl:for-each select="./parts">` and for some reason the code I have doesn't seem to work. I am not sure how to implement it. I am getting this error.

I have this code and this doesn't work.

```
<xsl:for-each select="./List">
  <fo:table-row>
    <fo:table-cell border="solid 1px" text-align="center">
      <fo:block font-size="8pt"><xsl:value-of select="group" /></fo:block>
    <fo:table-cell>
  <fo:table-cell border="solid 1px" text-align="left">
    <xsl:for-each select="./parts">
      <fo:block font-size="8pt"><xsl:value-of select="partNumber" /><fo:leader />
      </fo:block>
    </xsl:for-each>
  </fo:table-cell>
 </fo:table-row>
</xsl:for-each>

```
