If you have values across a report horizontally, you can add up all the values in a new text box. For example, if you have three fields across lets say the field names where x, y, and z respectively
Values in fields xy&z NEW TEXT BOX
23 45 78 =X+Y+Z
x y z
the field 23 is named X, 45 is named Y and 78 named Z. In the new text box where you want to see the sum type the above, =X+Y+Z would report the sum or 146
Let me know if you need any more help
