The problem is that a variable name is an XML QName, which can include 
hyphens.  Without any spaces, the select value is parsed as '$' 'pm-' '$' 
'hourMinutes' - in other words, a variable indicator, the name of the 
variable 'pm-', and then another variable indicator, which isn't legal 
there.  Instead, try

<xsl:variable name="minutes" select="$pm - $hourMinutes"/>
