try this
In the Data Source add a new Select filed like
(field1 - filed2) alias TotalSubst
then in the Report use TotalSubst as a Total (sum) field

Thanks , Gena but I don't really understand . Let me explain myself again i have two fields Dr and Cr. I am able to get the total for Dr and Cr using the report wizard. Now I have inserted a label in the report to display Balance which is Total Dr - TotalCr . Please help me , I will make a donation.

Open your Report
click on Data Source
select SELECT
in the Column/Expression write
(Dr - Cr)
in the Alias write what you want, like
SubstField
to see/check you can click on Review data - you will see a new field with the calculation
Then go to Designer of your Report, add new Label as usual, make it sum and use SubstField field

Another way to do it is simply to create a session variable in the before show for the two labels and then use those to calculate in the before show of the result label.

Great!
BTW withing Alias way you can make great things. For example, lets say you have date field (in standard mysql format yyyy-mm-dd HH:nn:ss) and want to Group just by years? Just create alias
year(my_date_filed) alias as MyYear
and the use MyYear as a GROUP BY!
etc etc So you can easy use any mySQL operations!
