How to sum rows above last transaction!?

[#1]

Hi i am quiet new to QW and i hope some one can help with my problem.

I wanna make a bar chart containing bars over ages and value of the stock, but i only wanna show stock until Qty <= ENTEREDQTY

ex.     Date 31-07-2013. QTY is lower then ENTEREDQTY here i whant to date returned in a new colum - DateFlag

          Date  31-08-2012 QTY 1+23 = 24 here i what the same.
somehow sum rows above to compare with value in stock?

I wanna do this in the scrip because i dont need the data if

ITEMNUMBER	ITEMGROUP	=Date(DATE)	sum(QTY)	sum(ENTEREDQTY)	sum(VALUE)	Stockvalue

RESJLG1120515	17JLG	30-04-2009	5	24	33	0
RESJLG1120515	17JLG	31-10-2011	6	24	39	0
RESJLG1120515	17JLG	31-08-2012	1	24	7	7
RESJLG1120515	17JLG	31-07-2013	23	24	150	150

right now i use

if( sum(ENTEREDQTY) >= rangesum (below(sum(QTY),0,sum(Total QTY))), Sum(VALUE))

this work in a table chart but now in bar chart, if the first value in QTY is below ENTEREDQTY, If there is a rest i want the rest from next transaction
