The error message means what it says: xsl:value-of requires a select
attribute. If you want to output the string value of the context node (I'm
guessing), then use <xsl:value-of select="."/>.

Your URL Lab_Number/Age"&value=" is also wrong. An ampersand in an XML
document must be written as &amp; (that's &_amp; without the underscore).
