Can a field on a form be updated (like with the condition - "Update a form field value") when the form is submitted

Can a field on a form be updated automatically (like with the condition - "Update a form field value") when the user hits the submit button AND the form is successfully submitted (i.e. as a paypal payment

What I am trying to achieve 

In essence I want to see if the user has paid so I can send out the product (digital curated report based on their responses to a questionnaire on the rest of the form)

I want to use this possibility with the edit link feature in Jotform.

I am putting a paypal pro payment section at the start of a large/long questionnaire form ( the user pays for a report based on the results of the questionnaire)

When the user completes the payment and and clicks submit an auto responder email gives them the link to now finish the form

I will use the conditional logic to hide show fields based on other field contents etc

Hello hartmutgunther,

I am not sure if I have understood your requirement correctly.

Do you want to update a form field value after the form is submitted successfully? Unfortunately we do not have such feature. Once the form is submitted, it will dynamically read the form fields and save the values. I am not sure at what level you want the field value to be updated. Can you please explain your requirement a bit more in details and we will see if there is any possibility.

We will wait for your response.

Thank you!

Hi. Thanks for the response. what I wanted was - when the submit button is hit it performs an action like triggering a conditional event. Simply put - when you hit submit a certain field is given a specific value - BEFORE the form goes off and is committed 

What your requirement needs is to make a custom script probably written in javascript as our current form builder function does not have that certain feature that will trigger an event once submit is pressed, As far as I know.
