RE: for-each and summing based on group

something like this format- the multiple colums are created by a date field which is not displayed here.
The main question is regarding the subtotals.

<begin>

<trade>
	<a>
	<step>
		<val>23</val>
	<step>

</trade>
<trade>
	<a>
	<step>
		<val>23</val>
	<step>


</trade>
<trade>
	<a>
	<step>
		<val>23</val>
	<step>


</trade>
<trade>
	<b>
	<step>
		<val>23</val>
	<step>

</trade>
<trade>
	<b>
	<step>
		<val>23</val>
	<step>


</trade>


</begin>

Hi Dmitri,
