Hi Houman,

>         <xsl:element name="$numberinfo">

You've missed out the {}s that tell the XSLT processor to evaluate the
variable reference (so it's trying to use the string '$numberinfo' as
an element name). You need:

  <xsl:element name="{$numberinfo}">

(I make this mistake all the time.)

Cheers,

Jeni
