I want to sum number in Column V if two conditions are met.
Condition 1: Data in Column K = SFD
Condition 2: Data in Column AT = value in cell H2 on another Sheet.

Dim Quarter As String
Quarter = filtercontrolSheet.Range("H2") contents of cell is 2009/4

I've tried the formula but get error message "Invalid number of arguments"
Thanks for the assistance.

StatsForm.TextBox9 = Application.SumIf(planDataSheet.Range("K2:K" & Endrow),
"SFD" And planDataSheet.Range("AT2:AT" & Endrow), Quarter,
planDataSheet.Range("V2:V" & Endrow))

I've also tried replacing the And joiner with * to no avail.
