Oh my. Wish you told what you were trying to do from the start. This is the worst way to get totals IMHO. Why do you sum each time you change a value in a column. Other rows have old values and no need to calculate again.
All you need is an initial sum. Store the result somewhere. Then when a column value changes add (NewValue - OldValue) to StoredTotal.
