Add row total

[mpainch]

Hi,
I am new to CR and I have been trying for hours to add up the numbers presented in a row for CR10.0. I cannot get it.

Row would be like this

Microfilm Voided Client Rev Total
4 6 2 12
3 3 3 9

How do I get 12 and 9 calculated? I have tried formula and running total.

Formula:
Microfilm + Voided + Client Rev

And nothing shows up when I run the report. What am I missing?

I assume that's not the actual formula :)
If these values are coming straight from the database then try

whileprintingrecords;
{table.microfilm} + {table.voided} + {table.clientrev}
