current() of current()

hi,

simple question yet its got me stumped.

<xsl:for-each select="a">
	<xsl:for each select = "//b[@aref = current()/@ref]">
		<xsl:value-of select = "//c[@aref = current()/current()/@ref"/>
	</xsl:for-each>
</xsl:for-each>

the current()/current() bit is illegal but how should you write it? 

Thanks,

Steve.
