I have a macro that when a name is entered in cell A1 a pop up window appears
asking for the birthday of the person who's name was entered. The birthday
date is then entered into cell A39. The macro works great this far. The
problem is that when the name of the person in cell A1 is deleted, I need to
have the birthday date also deleted in cell A39. What is the best way to do
this? Please help me soon!
See the coding below:

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo stoppit
Application.EnableEvents = False
If Target.Address = "$A$1" And Target.Value < "" Then
B_Day = InputBox("enter your birthday")
Range("A39").Value = B_Day
End If
stoppit:
Application.EnableEvents = True
End Sub

THANKS in advance!
