It would be much more efficient to go <xsl:variable name="notesleftmargin" select="ancestor::dxl:richtext//dxl:pardef[@id=$pabid]/@leftmargin"/> which defines the variable to be that attribute node, or even <xsl:variable name="notesleftmargin" select="number(ancestor::dxl:richtext//dxl:pardef[@id=$pabid]/@leftmargin)"/> which defines it to be a number. <xsl:variable name="leftmargin" select="$wert - 1"></xsl:variable> <xsl:if test="number($leftmargin) < 0"><xsl:variable name="leftmargin" select="0"></xsl:variable></xsl:if> This is trying to declare leftmargin after it has already been declared. You can't do that. You can not declare a variable that is in scope. (And of course you can't change the value of a variable once it is bound.)
