Sum a formula field [RESOLVED]

[usamaalam]

This is the formula called forTotal which shows amount in Dollars.

Sum ({Maintenance_ComplaintDetail.Charges}, {@Year})

Another formula called Year is :

Dim strArray() As String
strArray = Split(CStr({Maintenance_Complaint.OrderStartDate}),"-")
Formula = year(cdate(Left(strArray(3),2) & "/" & strArray(2) & "/" & strArray(1)))

Thanks.
