Watch for word wrap:

Private Sub CheckBox1_Click()
With CheckBox1
If .Value = True Then ActiveSheet.Range("A2").Value =
Range("Sheet2!$B$4").Value
If .Value = False Then ActiveSheet.Range("A2").Value = ""
End With
End Sub

or possibly
Private Sub CheckBox1_Click()
If CheckBox1.Value = True Then
ActiveSheet.Range("A2").Value = Range("Sheet1!$B$4").Value
Else
ActiveSheet.Range("A2") = ""
End If
End Sub

How do you make if True, Display the value of Sheet2 Cell B4? Below will
not work.

Private Sub CheckBox1_Click()
With CheckBox1
If CheckBox1.Value = True Then ActiveSheet.Range("A2").Value =
"Sheet2!$B$4"
If CheckBox1.Value = False Then ActiveSheet.Range("A2") = ""
End With
End Sub

Thank you
