Apply formula at result level

Question

Hi,
I need to build a report to get a KF of inventory turnover, the formular used is:
<i>turnover =total consumption / average stock</i>
while we use the formular below to get the
<b>average stcok =(begin of stock + n stock at month's end)/(n+1)</b>
what I need is to based on user's date input(let's say 09/2005 to 11/2005 for example),
1,get the "total consumption" for Oct and Nov,
2,and also get
"average stock" = (Stock at Sep + Stock at Oct + Stock at Nov)/(2+1)
3, get the turnover = "total consumption" /"average stock"
let's say KF "Total cnsumption" for 10/2005 is 10, for 11/2005 is 20. so <b>"Total cnsumption" for Oct and NOv</b> will be 10+20=30;
and if KF "Stock at Sep" = 12, "Stock at Oct" is 24,
"Stock at Nov" = 30
then <b>"average stck"= (122430)/(2+1) = 22</b>so the "turnover" will be
<b>"Total cnsumption"/"average stck"= 30/22= 1.36</b>
I am not sure how the report lay out will be, but as long as i can get the turnover based on teh user input's month during, that would be good enough. so probably the report will look like:
"Month"  "Totalcnsump" "Stck"  "averageStck" "TurnOver"
09/2005                  12
10/2005       10         24       
11/2005       20         30        
<b>result:       30         66       22         1.36</b>
Does any one have any idea how to make it done???

Dear Ping,
  This may not suit your requirements perfectly.
  But if your report layout is "fixed," how about adding a formula in the XLS workbook for example at column "G" such as:
  = IF(cell = "Result", apply the turnover formula cell1/cell2, else 0).
  As I have said, this is not the best way to do it.
  How about defining 2 structures in your query and try the options using cells definition in the query designer. You may wish to try and have a look at it for other possible solutions.
  Thanks a lot.
