Values In Column Based On Multiple Criteria

Option Explicit
Dim lastrow As Long, t As Long
Sub Method()
lastrow = ActiveSheet.UsedRange.Rows.Count
For t = lastrow To 1 Step -1
If Cells(t, 8).Value <> "" Then
If Cells(t, 9).Value = "Y" And Cells(t, 10).Value = "" And Cells(t, 12).Value > _
6 And Cells(t, 12).Value < 60 Then Range(t, 25).Value = 20
End If
Next t
End Sub

Alright, the above code is not working. I am not sure if it is the write part (t,25 value) that is wrong. I want the Y column to be written with a method numbered "20" if the conditions (H is not null, J="Y", K="", and 6<M<60). I have numerous other methods to put in. The reason I'm not doing Case Statements is this is jsut to write the basic code, and then I will have to move it over to ReportSmith using ReportBasic.
