Hi All

I am new to Zoho and am trying to figure out if there is a way to see the value of a particular stage at a given point in time.  The basic idea is to see the total value of each stage of the pipeline at the end of each week/month.  This will allow me to see the trends at the end of each period of time

I can figure out how to see values when there was an action such as modified, closed, updated etc, but not just to see the total value at the end of each period. 

Any support will be gratefully received.
