I would like to set up task reminders in excel 2007 based on coloums & rows.

A window that would pop up 5 minutes before a mentioned time in a row.

Column A Column B Column C
John 29 Aug 4: 15 pm
Ryan 30 Aug 3:00 pm
Lisa 27 Aug 5:00 pm

In the above columns as soon as it is 4:10 pm on 29 August, can I get a popup with the text in columnA "John".

I would be grateful if anyone could help me out with this one... Kinda stuck here....

Regards
Krishna
