I am trying to make it so a user cannot submit the same exact information twice. I have a data page that accepts a, Name, Country, State, and City and is added to a table. However you can resubmit the same info over and over again filling the table with redundant information. I thought about setting the table fields to Unique but that doesn't really do what I want. I need to be able to enter very similar data as different entries, but not allow identical data. So an entry of, Remote Diagnostics, USA, New Jersey, and Toms River, can not be entered twice but allow that entry and Remote Diagnostics, USA, Georgia, and Toms River. What I need is a Unique entry and not just a Unique field.
I tried searching for this but was unable to find anything. If anyone has an answer or can link me to something I missed it would be much appreciated.
Thank You
