I am trying to get daily totals sumed and put into a monthly
worksheet. I have been using SUMIF comparing the month and year of
each payment.

Here is the formula.

=SUMIF(MONTH(Payments!b7:b3000)&YEAR(Payments!b7:b 3000),
MONTH(B39)&YEAR(B39),Payments!F7:F3000)

Excel is saying there is an error but when I look art the edit formula
area is seems to calculating correctly.

Can you help me?
