VBA - Change Posting To Different Worksheet

Adjust this code to output the differences in WS3 instead of WS2. I'm having trouble changing the worksheet in the code.

Ta in advance. Chuf


Sub CompBelowCol()
Dim ListA As Range
Dim ListB As Range
Dim c As Range
WB1 = ActiveWorkbook.Name
WS1 = "EE"
WS2 = "13"
WS3 = "New Order"
Set ListA = Workbooks(WB1).Sheets(WS1).Range("A1:A" & Cells(Rows.Count, "A").End(xlUp).Row)
Set ListB = Workbooks(WB1).Sheets(WS2).Range("M1:M" & Cells(Rows.Count, "M").End(xlUp).Row)
For Each c In ListB
If c.Value "" Then
If Application.CountIf(ListA, c) = 0 Then
With Cells(Cells(Rows.Count, "T").End(xlUp).Row + 1, "T")
.Value = c
End With
End If
End If
Next c
End Sub
