I am trying to create an IF that looks for a date range from one column and
then counts items in another column. The formula I have below is not looking
at the MONTH field. Any suggestions? Thanks!

=IF(MONTH(SHEET1!A2:A500*(2)),COUNTIF(SHEET1!G2:G5 00,"Successful"))

MONTH is looking at SHEET1 in cells A2 to A500 for February (2 month)
The next statement should look at only February data and then count how many
times the word "Successful" is found.
