delete row based on criteria of value in two columns

I'm trying to write a vba that will delete a row based on the criteria of two columns. In this case if the value of the two columns is zero (or null) or the value is an error, I want the row to be deleted. I tried the following code, but nothing seemed to happen. Your help is greatly appreciated.

Sub cleanup()
     
     
    Dim i As Long
    Dim LastRow As Long
    LastRow = 10
    Sheets("AX").Select
     
    For i = LastRow To 3 Step -1
         
        If (Range("e" & i).Value = 0 And Range("f" & i).Value = 0) Or IsError(Range("e" & i).Value) Then
        Rows(i).EntireRow.Delete
        End If
        Next i

End Sub
