The following code is giving me a Application Defined or Object Defined
error trying to set a formula for cell I for each row:

Dim wb As Workbook
Dim ws As Worksheet
Dim res As Variant

Set wb = ActiveWorkbook
Set ws = wb.Worksheets("Data")
Set rng = Cells(Rows.Count, 1).End(xlUp)


For i = rng.Row To 2 Step -1

alias2 = Sheets("Data").Rows(i).Cells(3).Value

ws.Cells(i, "C").Value = Application.VLookup(alias2, _
Sheets("PolicyStatus").Range("A:B"), 2, False)
'The above works

'Below getting error

ws.Cells(i, "I").Formula =
"=IF(AND(RIGHT(H2,3)='001',RIGHT(H2,3)<='275'),'F TA', " & _
"IF(AND(RIGHT(H2,3)='276',RIGHT(H2,3)<='299'),'Sp ecial
Retired',IF(AND(RIGHT(H2,3)='300',RIGHT(H2,3)<='8 99'),'BROKER', " & _
"IF(AND(RIGHT(H2,3)='900',RIGHT(H2,3)<='999'),'FR ','UNASSIGNED'))))"
