How can you delete duplicates?

Can you please let us know what kind of duplicates are you talking about? Is it duplicate submissions, or did you mean duplicate fields on your form?

To delete submissions, you can go to your submissions page, and use the Delete button from the top right corner.

To delete form fields, open your form for editing in the Form Builder, select a field you wish to delete, and click on its little X-shaped icon in its top right corner.

To delete forms, you can go to your My Forms page, click on the form you wish to remove, and then on the Delete button in the header. You may need to also Purge a deleted form from your Trash folder so that it is completely removed from our system.

I hope this helps. If you were asking about something else, please describe it in more detail, and we will be happy to help.
