Grouping question

Hi,

I'm having a grouping issue. In my case root tag is "Statements" and
under Statements I can have multiple Statement tags. I'm using muenchian
method for grouping but I need to group within a Statement tag as oppose
to the whole xsl doc. Now within each Statement I have to calculate
month totals. Since all the months and dates are dynamic so I'm using
grouping to get a set of amounts according to the month and year. As you
can see in the output, amounts from the 2nd statement node are showing
up in the first statement since key is getting applied to the whole xml
doc. I need to restrict it to the current statement node only. Is there
any way to do it? How can I specify current id or any other attribute of
the statement in the key or any other idea???

Hope I made myself clear. Attached are my test xml and xsl scripts.

Thanks in advance,
Nishma

My output...

Statement:1

    	Date 2004-07-10 amount: 2.00
    	Date 2004-07-08 amount: 1.00
    	Date 2004-07-19 amount: 3.00
     MONTH TOTAL : 7.00
