(the default for d-o-e
is "no" so you don't have to say it)

Right.  The scope of a local
variable is the following siblings and 
their descendants.  There are no such
following siblings.

there be a simpler way to do this?

Yes ... don't use the flag.  Something
along the lines of:

  <xsl:template name="getOrderSource">
    <xsl:for-each
select="/ns0:Transaction-850/ns0:Loop-N1">
      <xsl:choose>
       
<xsl:when test='ns0:Segment-N1/ns0:Element-66 = "21"'>NAEDI</xsl:when>
       
<xsl:otherwise>NAEDIBrokerage</xsl:otherwise>
      </xsl:choose>
   
</xsl:for-each>
  </xsl:template>

I hope this helps.

Thanks
Ken. The problem with the above approach is that if there are 3 Loop-N1's
then the output would be:
<corecom:ID>NAEDIBrokerageNAEDIBrokerageNAEDIBrokerage</corecom:ID>

Thats why
I was trying to set a flag inside the loop and then return a Single 
value.
