Real time Code Check

Hello,

I have managed to create a code at the beginning of the survey. I want to see if there is way to check if this code is unique compared to other previous submissions.
The purpose is to avoid having a survey filled by the same person.

Thank you for your support.

Welcome back to the community, @qrd_sanad! You could do this by using the Dynamic Data Attachment feature as outlined in this post discussed previously:

Thank you for your reply. However, i am afraid this didn’t work.
I already have a code that is automatically generated based on demographic questions, but before proceeding with the long survey, i want to make sure that we are not interviewing the same person (same code). I don’t have two forms, i want to check the code against previously submitted codes.
Thank you for your help.

Hi @qrd_sanad, @Kal_Lam’s topic is about linking a form to itself. You don’t need two different forms to achieve that.
