Client originally wanted sum values entered in radio boxes (at top) to be calculated in "Donation" box at bottom ("R1dollars" starting on line 392). You guys helped me with that.
Now the client has added an additional box where the donor can add an additional numerical contribution manually. (starting line 319)
We need the sum total of the manual input to appear, in addition to the sum of the radio buttons, to be calculated in the bottom Donation box (starting line 392)
