Hi
I have a workbook in which columns on some sheets are hidden for printing purposes.The issue i have is people hide these columns and forget to unhide so information goes un-noticed.It there a way that when someone goes to shutdown the workbook that it cannot be closed unless the hidden columns are made visible.Can this only be achieved by VBA or are there non VBA ways to achieve this action?
Thank you
James
