Unique question to disallow duplicate entries not working

I have a uniqueID field which is calculated based on values from three other fields.

This uniqueID field is also set-up in Form Settings for unique answers.

However, it still allows duplicate values to be input and submitted.

Please check and revert.

Thanks.

I have cloned your form and testing this issue but it is taking some time. I will get back to you on this soon.

Please accept my apology for the delay.

I cloned your form and deleted all form fields and just retained the fields which you have used in condition to insert value in "unique Id" field. When I tested your form, it seems to work as expected. I was not able to submit the form with the same "Tour Code", "Name" and "Primary Email" value. Please check the screenshot below:

I also went ahead and tested your form and it seems to work just fine. Please check the screenshot below:

I would suggest you to please test your form again and get back to us if the issue persists.

Yes.  It does work correctly now.  Thanks for your help.

Best regards,
