how to I retrieve information saved on a jotform platform please?

Please note that you can go to your form's table to view all the submission data that you have received in your form. You may like to take a look at the following guide, which should help you: https://www.jotform.com/help/269-how-to-view-form-submissions/

I did check your account "susancourtney0" and found that you have not built any form yet. This account was just signed up today. Do you have any other account? Please let us know your account username or the email address you have used in your other account profile? Alternatively, you can also let us know any of your form ID, form URL or webpage URL where you have embedded your form and we will take a look.

We will wait for your response.
