I am getting help, yet I need further help. The formula I post below, works
for B3 and to the right. I need it to work exactly the same from B3 thru B100
and have numbers in the entire row work as B3 does . That is B49 moves to
C49, C49 moves to D49 etc.

Do I need a code for each line? That would seem horribly wrong.
Thank you: Check this. Works great for one line B3. It's a great code

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address < "$B$3" Or _
IsEmpty(Target) Or _
Not IsNumeric(Target) Then
Exit Sub
End If
If MsgBox("Use the new value " & Target & _
" as new Daily Entry?", vbYesNo + vbDefaultButton1 _
+ vbInformation, "Verify Entry") < vbYes Then
Target.ClearContents
Exit Sub
End If
'overwrite E3 with D3
Range("E3") = Range("D3")
'overwrite D3 with C3
Range("D3") = Range("C3")
'overwrite C3 with B3
Range("C3") = Target
'clear B3 for tomorrow
Target.ClearContents
End Sub

Need B1:B100 to work this way
