I have searched and read the topics on this, however I am apparently below beginner and need someone to walk me through the entire process. I need an email sent to myself and 2 other co-workers one day before an item listed in my spreadsheet expires. I have the expiration dates are listed in column F. I have not entered any email addresses yet.I would like, as I have read in previous threads, for the system to open and check itself daily. Any help is greatly appreciated, and I will need a very basic, step by step hand holding description.
