Is there a way to avoid duplicate submissions by checking a unique field?Asked by aloprint on December 16, 2016 at 02:33 PM
I have a form for example with a field called TICKET the end user write your ticket number, for example 123456 (unique number)
It´s possible when press SUBMIT form, Jotform validate if these number 123456 exits previously?
Hello - There is a way to achieve that by setting a Unique Question to your form.
Just click PREFERENCES at the top of the FORM BUILDER > ADVANCED tab > pick the field that you want to be unique (in this case the Numero de Ticket field) as your UNIQUE QUESTION > SAVE.
