Total balance amount not displayed correctly

Question

i have shown my table below my problem is that the balance amount being displayed on form displays the total balance amount and total balance amount being displayed is the sum of all balance amount,hence the final total which iget at the end is incorrect and a huge amount,, while balance amount should be equal to expected amount and total balance amount should be total of all balance amount..less any payments made by the client..
i have displayed below only the part of script...
