[xsl] Record count

["Waqar Ali" <waqarali_pk@xxxxxxxxxxx>]

Hello:

I need to print the number of records I looped thru in my for-each loop in 
the TRAILER record. I guess last() may do but variables dont seem to work 
out of the template scope. Please see the example below and I'll be greatful 
if you can suggest a solution:

 <xsl:template name="Header" match="/">
   <xsl:text>HEADER</xsl:text>
 </xsl:template>

 <xsl:template name="Detail" match="/">
   <xsl:for-each select="Records/Record">
     <xsl:variable name="record_count" select="last()"/>
   </xsl:for-each>
 </xsl:template>

 <xsl:template name="Trailer" match="/">
   <xsl:text>TRAILER</xsl:text>
   <xsl:value-of select="$record_count"/>
 </xsl:template>

 <xsl:template match ="/">
   <xsl:call-template name="Header"/>
   <xsl:call-template name="Detail"/>
   <xsl:call-template name="Trailer"/>
 </xsl:template>

Thanks.
