=IF(Enter!C2:C1690=March,SUMIF(Enter!
$B$2:$B$1690,$A9,Enter!$D$2:$D$1690),0)
Enter! - is my sheet with data
C column contains dates
B column contains account info
D column contains $

I am trying to say that if Any date in C column is in
March, perform the
following calculation. Any suggestions?

Thanks!
