Avoid duplicates in a repeat group

Dear all,

Using repeat group, I am collecting NIC (a unique identifier) of persons participating in an activity. I want to make sure that no NIC is entered twice. What can be the most suitable way to implement that.

Please guide.

Best Regards

Hi there,

There isn't an easy way to do this while you are in the repeat.

If you
want a hard way, try
