addition of new data wrongly creates new record instead of updating??-

4
i have just changed a field so that it automatically grabs x/y coord for a site from an arcmap doc. problem is that as it does this it creates a new record for each site instead of updating the existing record for each site. within the site table there is an indexed autonumber field but the site name field is not indexed, so cannot prevent duplication within site field, hence the problem

Any ideas out there?,
