YTD totals not showing up

Hi experts,

I am trying to create a report that shows the YTD totals but those values are not showing up.

What I am seeing is the same for all measures dimension members.

Ex:-

Account Time          Periodic     YTD

Margin Jan 2015      100               100

           Feb 2015     200               200    

           Mar 2015     300               300    

           Q1               600               600

How can I derive a report that shows

Account Time          Periodic     YTD

Margin Jan 2015      100               100

           Feb 2015     200               300    

           Mar 2015     300               600    

           Q1               600               600

Thanks
