    Issues with assigning a unique number

    Asked by K9SD on September 11, 2015 at 11:53 AM

    Form in question:


    I need to assign each form that is completed a unique number and have used the jotform plug in to do that.  However, it is giving them a different number in their "thank-you' message (one number lower, I think) than it is showing in the form submission info that I see.  It is also showing the same (wrong) number to folks that fill out the form more than once (for each of their dogs) instead of showing the number assigned to each form/dog.

    I really need this fixed quickly as I already have to contact several people to let them know their registration number is incorrect. Unless I can assume for sure that the number they saw is one less than what I see in the form data and I'll just change my own records. But don't want to have to do that with everyone and still need to address the multiple form submission issue.

    I used the widget and in the "Thank-you" message the person gets after going to paypal, I added the {unique ID} designation so the customer can see their assigned number AFTER they pay. But it seems to be putting a number that is one less than what I see on their submission.  So in the form submissions, if the number assigned to their form/dog is 19, they see 18 on the thank you message.  Also, when a person fills out the form multiple times (to get a number for each of their dogs) the "thank-you" message they see is showing them the same number for each of their dogs. So if the first dog they registered got 18, the rest of their dogs also show 18 even though each one is a completely separate form and payment for the rest of their dogs. I do see different numbers assigned to each dog in the form submissions.

    So I need the person to see the correct number in the thank-you and I'm not sure WHY it's not showing them the correct number.

    I have cloned your form into my account and testing it on my end with Sandbox mode (not with real payments), and the Unique ID was generated correctly.

    I did see that the ID is not correct while the submission is still an Incomplete Payment (not yet paid), but once it is completed - the Unique ID takes the next available number.

    As you are using a required email field on your form, can you please try setting up an Autoresponder email to the person who filled out your form. This will make sure that your users receive an email each time they submit your form and pay. They will receive a separate email for each of their payments, so they would receive correct assigned ID for each dog.

    On the thank-you page, you can write that an email has been sent to {email} containing their dog's unique number. I hope this helps.

    I will also do some more tests with different browsers over the weekend to see if PayPal is showing the same old thank you page after payments in some scenarios, or if it's correctly loading a new thank you page each time. Thank you.

    Thank-you! I set up the auto email feature (and changed the thank-you message) and hopefully that will solve the issue.
