Description of the issue
My database consists of records. Every single record is suppose belong to only one unik person.
Therefore i have created a field called CPR. The CPR field is a number field with consists of 10 digits.
The 10 digits are unique because no person shares his/her digits with another person.
Steps to reproduce the problem
My wish is to have another field called check cpr. In this field i can put in the digits and then by a click button or another function it will calculate through every record to see if the person already exists in my database. Because i dont wont to have a person to figure in two or more records
A message saying if the person already exist and another message saying if the person do not exist.
