[Please note that I use the Calculated Member Expert" (not the Preview window) screen to manage my Calc Members.
I am looking to display a Calculated Member Row that shows me the difference between the 2 Month values for a given year.

I would like to take the (Larger Year total) - (Smaller Year Total) = Change in Rev (Calculated Member Row)
In some cases, there might not be 1 of the 2 years depending on if a Customer was lost or added.
What would be the syntax for for the Insertion Formula and Value Formula?
I would like the "Change in Rev" Row to appear below the "SubTotal" (crossed out in Red)...Ideally I would like the Subtotal Suppressed because I do not require it, BUT if you suppress the SubTotals, the Change in Rev Row will not appear.
Any help would greatly be appreciated.
