Hi Stuart, > In the XSL below I'm trying to pass a optional parameter called > "alignment" into a template. When the parameter is not passed into > the template I want to assign a default value (left) to the variable > "alignment" You can use the select attribute or the content of the xsl:with-param element to set the default value of the parameter. In your case, you should use: <xsl:template name="writeline"> <xsl:param name="text" /> <xsl:param name="alignment" select="'left'" /> </xsl:template> > <xsl:template name="writeline"> > <xsl:param name="text"/> > <xsl:param name="alignment"/> > <xsl:variable name="alignment"> > <xsl:choose> > <xsl:when test="$alignment"> <===== This syntax causes error > <xsl:value-of select="$alignment"/> > </xsl:when> > <xsl:otherwise> > <xsl:value-of select="string('left')"/> > </xsl:otherwise> > </xsl:choose> > </xsl:variable> [snip] > </xsl:template> Your problem in this template is that you're declaring a variable with the same name as an existing parameter. You can't have a variable and parameter with the same name, nor can you change the value of a variable or parameter once it's been set. I hope that helps, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
