counting different client

[JohnC#]

I need to count how many different client come to get our service.

When a client come, a new record is create containing :is client # and the date . Is there a way to know how many different client come :

Thanx

If each visit is a record, then you could create a self-join relaitonship within the file using the client # on both sides of the relationship. Then create a calculation field which is set to Count( SelfJoin::client # ). This will give a count of the related records, which should be a count of the visits.
