Hide column in a web intelligence report

Hi all,

I have created a inventory aging report for the for the days buckets <14,15 to 30,31,60,61 to 90.My report to be calculate

based on last movement date.The  lay out of my report below :

When i removed the Movement date,the data goes wrong.

I dont want to display the movement date in my report,- ut increases the no of rows in the report & it gives the movement date from the first transaction.I would like to show the value in one line without movement date like

Stock Value      <= 14     15 - 30       31 - 60    61 - 90    91 - 180    >180

890                       0.3        0               0            0.6               0          0.
