I have a matrix that calculates averages but I need to add a total of the averages at the end of the matrix. Now if I use =sum(avg(FieldName!.Value), it does not work since SSRS does not support aggregate of aggregate. Please help how can I sum the averages. My matrix looks like below
| Product Type | Interest Income | Fees Earned | Average Balance |
| Auto | $105.45 | $172.06 | $561.32 |
| Residential | $2,706,305.07 | $29,996.91 | $406,759.58 |
| Commercial | $723,965.83 | $184.85 | $1,363,393.48 |
| Total | $3,430,376.35 | $30,353.82 | xxxxxxxxxxxxxxx |
I need the sum of the average balance where the xxxx is. The amount seen in the average balance column are the averages.
