Hi Vivek, XSLT does not allow variables to change. Think of them as constants. You'll need to rethink your approach, I'm afraid.

When I try to use it subsequently it gets reinitialized. Here's the code. <xsl:variable name="whead" select="'No'" /> <xsl:template match="/newsletter"> . . <xsl:apply-templates select="content/article" mode="proc_webcastheader" />. </xsl:template> <xsl:template match="article" mode="proc_webcastheader"> <xsl:variable name="artclass" select="normalize-space(metadata/article-classification/.)" /> <xsl:if test="contains($artclass,'Biz-Webcast')"> <p><xsl:value-of disable-output-escaping="yes" select="$whead"/></p> <IMG src="http://www.sas.com/subscriptions/images/hdr_webcast.gif"></IMG> <xsl:variable name="whead" select="'Yes'" /> <p><xsl:value-of disable-output-escaping="yes" select="$whead"/></p> </xsl:if> </xsl:template> In the second template when I print whead before the <img> it shows 'No' for all articles even if I set it to 'Yes' after the <img>. Any clues on how to retain the value of the variable? Thanks Vivek
