Two things wrong here, using xsl:variable with no select attribute
produces a result tree fragment which you probably don't want here, use

	<xsl:variable name="result"select="$last"/>

But the scope of a variable binding is its containing element which in
this case is the xsl:when so  this variable will go out of scope before
it is ever used.

which is why you get an error here

     <xsl:value-of select="concat('slide',$result,'.html')"/>

There is no result variable defined at this point.
