Try:
<xsl:value-of select="/DOCUMENT/Image_A/IMG/@HEIGHT - /DOCUMENT/Image_B/IMG/@HEIGHT"/>
...which has the same effect as:
<xsl:value-of select="number(/DOCUMENT/Image_A/IMG/@HEIGHT) - number(/DOCUMENT/Image_B/IMG/@HEIGHT)"/>
Of course, MSXML 2.0 doesn't support number(). Hopefully you've read
http://www.netcrucible.com/xslt/msxml-faq.htm and aren't still using the
old syntax.
