---Using formulas you can link one cell to another. In B1 use the formula
=A1
to link B1 to A1...Any changes made to A1 will be reflected in B1
---If you are looking to reflect changes made in A1 and B1 to reflect in
both cells you will need to use a macro. Right click the sheet tab >view code
and paste the below code.
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
If Not Application.Intersect(Target, Range("A1")) Is Nothing Then _
Range("B1") = Range("A1")
If Not Application.Intersect(Target, Range("B1")) Is Nothing Then _
Range("A1") = Range("B1")
Application.EnableEvents = True
End Sub
