get current position as parameter

From: "Ghena" <lastminutesud@-----.--->
To: NULL
Date: 9/9/2006 2:40:00 PM

I have this
situation:

<xsl:for-each select="../../ReturnList/Return" >
xsl:sort="sum(../../OutwardList/Outward[$pos]/Price/Amount|../../ReturnList/Return[position()]/Price/Amount|$prezzo_gruppo)"
order="ascending" data/type="number" /><br/>
</xsl:for-each>

but the sum is not right becouse the position value is not understanded
from xpath...

I check it by a comparing:

<xsl:for-each select="../../ReturnList/Return" >
<xsl:variable name="posrt" select="position()" />
<xsl:value-of
select="sum(../../OutwardList/Outward[$pos]/Price/Amount|../../ReturnList/Return[$posrt]/Price/Amount|$prezzo_gruppo)"
/><br/>

<xsl:value-of
select="sum(../../OutwardList/Outward[$pos]/Price/Amount|../../ReturnList/Return[position()]/Price/Amount|$prezzo_gruppo)"
/><br/>

</xsl:for-each>

Wich is the right way to get the "position()" value  in this case
without using a variable?
