I need a code for a workbook of 3 sheets. This code must do flashing cells
(not fonts) and the sheets are named ( Serie A, Serie B and Serie C).

I want these flashing cells as soon I open the workbook.

Serie A ( Cells AN6 and AW6)

Serie B ( Cells AN6 and AW6)

Serie C ( Cells AN6, AW6, AN83 and AW83).

Thanks for your help.
