Offhand, I'd say the problem is b/c position() does not take any arguments.
Try 

	xsl:if test="b[position() = last()]"

if you're testing for b being last.  last() does not take arguments either.

><xsl:template match="a/b">
><xsl:if test="position(..)=last(../../a)">&nbsp;&nbsp;&nbsp;&nbsp;
></xsl:if>
