Instead, write <xsl:variable name="gearMid" select="round(count(//rec_gear_sec/*) div 2)"/> You want a number, not a result tree fragment containing a text node whose string value is the decimal representation of a number. You also want to avoid writing three lines of code that give you roughly what you want when you could write one line that gives you exactly what you want. Michael Kay http://www.saxonica.com/
