Not sure why yours is working.  Are you using:

      <xsl:value-of select="../../FIELDS/HEADER"/>
      <xsl:if test="../../FIELDS/*[name() = 
concat('TITLE',current()/@NUM)]">
           <xsl:value-of select="../../FIELDS/*[name() = 
concat('TITLE',current()/@NUM)]"/>
      </xsl:if>

This one in my file always puts the 2 together if the TITLEx exists. 
Otherwise only the HEADER is shown.

Thanks,

Tom
