compute sum of field on report

I have:

break on received_amount nodup
compute sum of received_amount on report

If my output looks like this:

Account Number      Received_amount    Charge#
--------------      ---------------    --------
       1                 100              88
										  90

       2                  30               45
	   3                  50                 32
											   34
                   ---------------
					   330

Now, I don't want 330 , I want 180. it is adding the Non-seeable fields into my sum... How do I just add what I see on the report?
