Question 1.
I have a code (below), that blinks certain cells in a workbook where it works
perfect, but when I protect each sheet it stops working. (Protect without
giving a password, just click on protect worksheet)
Is there a solution by modifying the code? Please if there is a solution,
will you please arrange the code for me, cause I am a beginner in VBA.

Question 2.
Can someone give me the colour codes. ( example 3 is for RED).

Thanks a lot.

Workbook code:
Private Sub Workbook_Open()
StartBlink
StartBlink2
StartBlink3
End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)
StopBlink
StopBlink2
StopBlink3
End Sub

Module Code:

Public RunWhen As Double

Sub StartBlink()
With ThisWorkbook.Worksheets("Serie A").Range("AN6,AW6").Font
If .ColorIndex = 3 Then ' Red Text
..ColorIndex = 31 ' White Text
Else
..ColorIndex = 3 ' Red Text
End If
End With
RunWhen = Now + TimeSerial(0, 0, 1)
Application.OnTime RunWhen, "StartBlink", , True
End Sub

Sub StopBlink()
ThisWorkbook.Worksheets("Serie A").Range("AN6,AW6").Font.ColorIndex = _
xlColorIndexAutomatic
Application.OnTime RunWhen, "StartBlink", , False
End Sub


Sub StartBlink2()
With ThisWorkbook.Worksheets("Serie B").Range("AN6,AW6").Font
If .ColorIndex = 3 Then ' Red Text
..ColorIndex = 2 ' White Text
Else
..ColorIndex = 3 ' Red Text
End If
End With
RunWhen = Now + TimeSerial(0, 0, 1)
Application.OnTime RunWhen, "StartBlink2", , True
End Sub

Sub StopBlink2()
ThisWorkbook.Worksheets("Serie B").Range("AN6,AW6").Font.ColorIndex = _
xlColorIndexAutomatic
Application.OnTime RunWhen, "StartBlink2", , False
End Sub
Sub StartBlink3()
With ThisWorkbook.Worksheets("Serie C").Range("AN6,AW6,AN83,AW83").Font
If .ColorIndex = 3 Then ' Red Text
..ColorIndex = 2 ' White Text
Else
..ColorIndex = 3 ' Red Text
End If
End With
RunWhen = Now + TimeSerial(0, 0, 1)
Application.OnTime RunWhen, "StartBlink3", , True
End Sub

Sub StopBlink3()
ThisWorkbook.Worksheets("Serie
C").Range("AN6,AW6,AN83,AW83").Font.ColorIndex = _
xlColorIndexAutomatic
Application.OnTime RunWhen, "StartBlink3", , False
End Sub
