Average Calculation in WEBI

Hi All,

I am new to SAP WEBI & IDT. I need to fix a formula in which Average calculation is wrong when one of the value is empty.

Eg If I have data for 4 days but one of them is empty then Avg = (A+B+empty+D)/4

this is how it is working, but some how the calculated avg is incorrect.

I am trying to use the built in function Average but still not able to make it work. I tried using property  " ;IncludeEmpty" too.

Any lead on this will help..

Thanks in advance...
