Deletion of line items

We need to remove a couple petition lines (people signed twice, and another is not in the petition area). 

Is that possible?

Hi Robert, thank you for contacting JotForm support.

Are you perhaps referring to the submissions on the JotForm Table?

Please note that the line/row represents the submission. You can delete rows by moving the submission to the trash.

I hope this helps. Let us know if you have further questions.
