Your code has For & Next,
But why Compile error: Says that "Next without For" ?

Static OldValues As Variant 
Dim NewValues As Variant 
Dim Changed As Boolean 
Dim i As Integer 
NewValues = Me.Range("T4:T31").Values 
If Not IsArray(OldValues) Then ' Only true on first run after opening Workbook
    OldValues = NewValues 
Else 
     For i = LBound(NewValues) To UBound(NewValues) 
        If NewValues(i) <> OldValues(i) Then 
            Changed = True 
            OldValues = NewValues 
            Exit For 
       Next
    End If     
    If Not Changed Then
      Exit Sub
