[EpiData-list] preventing duplicate entries

I am entering daily visit counts to walk-in clinics in our area. There 
are 6 clinics or sites. So a record is uniquely identified by site and 
date. Is there a way to prevent the entry of records with a site-date 
combination that duplicates a site-date combination that already exists 
in the database?

Thanks.
