The child template is treated specially; it is outside the scope of the calling template. To pass a variable to a called template, you need to use param and param-variable, like this: <xsl:template match="/"> <xsl:variable name="DebugOpts" expr="abc123"/> <xsl:call-template name="childTemplate"> <xsl:param name="DebugOpts" expr="$DebugOpts"/> </xsl:call-template> </xsl:template> <xsl:template name="childTemplate"> <xsl:param-variable name="DebugOpts"/> <xsl:text>The value of $DebugOpts is: </xsl:text> <xsl:value-of select="$DebugOpts"/> </xsl:template> This technique can be used to pass parameters back and forth between templates. An increment function could be simulated this way. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
