sorry for so many posts.

Am not sure how clear I am heh

I have a spreadsheet with many names.. there will definately be lots of repititions of names and email addresses... I want an email to be sent to a person when they have an action due. A person in my spreadsheet may have 25 different actions/rows and on different days. If they have many actions due on march 1st.. I just want the spreadsheet to email them once instead of many times. If they have more actions due on march 2nd.. i'd like the spreadsheet to email them once on that day as well instead of many times.
