Many thanks Mukul!

One question - I'm getting errors in VS 2005 about the line that reads:
  <xsl:when test="$i <= $len">  (Character "<" is illegal in XML
attribute values)

I've tried the following and still get an error:
  <xsl:when test="$i le $len">    (Expected end of the expression,
found 'le '.  $i  -->le <-- $len)

What am I missing?
