Its normally a good idea to test your code before you post it :) Here's a working version: <xsl:template match="/"> <xsl:call-template name="repeater"> <xsl:with-param name="theString" select="'Hello'"/> <xsl:with-param name="numberOfTimes" select="20"/> </xsl:call-template> </xsl:template> <xsl:template name="repeater"> <xsl:param name="theString" select="''"/> <xsl:param name="numberOfTimes" select="0"/> <xsl:if test="$numberOfTimes > 0"> <xsl:value-of select="$theString"/> <xsl:call-template name="repeater"> <xsl:with-param name="theString" select="$theString"/> <xsl:with-param name="numberOfTimes" select="$numberOfTimes - 1"/> </xsl:call-template> </xsl:if> </xsl:template> cheers andrew --- Outgoing mail is certified Virus Free.
