        msgbox "Conflict"
        ActiveCell.Select
        Target.Interior.ColorIndex = 8`

Sub:

Public Sub LoopRows(Appserver As String, StartTime As Date, EndTime As Date)

      Dim x As Integer
      Dim NumROws As Integer
      NumROws = Range("Sheet3!C5").End(xlDown).Row - Range("Sheet3!C5").Row
      Worksheets("Sheet3").Activate
      Range("Sheet3!C5").Select
      msgbox Appserver
      msgbox StartTime
      msgbox EndTime
      For x = 1 To NumROws
        ActiveCell.Offset(1, 0).Select
        If (ActiveCell.Offset(0, 1).Value = Appserver) Then
             Dim RowStartTime As Date
             Dim RowEndTime As Date

                msgbox "Conflict"
                ActiveCell.Select
    Target.Interior.ColorIndex = 8

             Else
                msgbox "noConflict"
             End If
