You want 1 number but you are looping over <xsl:for-each
select="works_details">
and working out a number for each. As each works_details only has a
single "Work_Year child
Work_Year[last()] and Work_Year[1] are the same element, so you get 0 in
each case for the difference.
You want
<xsl:template match="artist_works">
<xsl:value-of select="
(works_details/Work_Year)[last()] - (works_details/Work_Year)[1]"/>
</xsl:template>
