I have written the following lines:
Range(Person).Select
If Range(Person).Select "" Then
resp = MsgBox("The person you have selected already has comments." &
Chr(13) & "Do you want to overwrite?", 4, WARNING)
If Response = vbNo Then
Windows("Personwin").Close
Exit Sub
If Response = vbYes Then
End If
End If
End If

Basically the person can change depending on the input. But, each person has
their own column and if the column already has comments, then I want to be
sure the user wants to write over these comments.

If the answer is 'no', then I want the window closed that was opened to
receive the comments (Personwin).

If the answer is 'yes', then I want the macro to continue with recording the
comments, etc.

When the macro runs and I click 'no', the macro continues instead of closin
the window and stopping.

Can someone please explain what I did wrong?
