Range("B5,B7,B12,B14,B19,B21,B26,B28").Select
Range("B28").Activate
With Selection.Validation
.Add Type:=xlValidateTextLength, AlertStyle:=xlValidAlertStop, _
Operator:=xlEqual, Formula1:="8"
.IgnoreBlank = True
.InCellDropdown = True
.InputTitle = ""
.ErrorTitle = ""
.InputMessage = ""
.ErrorMessage = ""
.ShowInput = True
.ShowError = True
End With
End Sub
