Calculate total of two fields

[eugz]

Hi All.
I try to generate a report. This report includes two fields with currency format. I need to calculate total of both fields for each person. When I do like =Sum([Field1]) and =Sum([Field2]) I got correct result for each field but when I do like =Sum([Field1] + [Field2]) I have a problem. I'm calculating in footer LastName. How to get a correct result?
Thanks.

Sum

How about:

=Sum([Field1]) + Sum([Field2])

Thanks for replay. But unfortunately it doesn't calculate.

Think it's

=[field1]+[field2]
