I need to capture someone's page 1 submission when they click next

How do I capture the info they filled out on page 1 when they click next??

It's possible, here's what you need to do.

1). Add a Get Form Page URL widget https://www.jotform.com/widgets/get-form-page-url

2). Add a Submit button beside the next button.

3). Add a condition that when the form page url widget contains "edit", show the page break.

4). You need to create a URL to redirect your users once they submitted the form https://www.jotform.com/help/211-setting-up-the-thank-you-page.

5). Add a redirect URL in your form's thank you page.

https://www.jotform.com/edit/{id}?jumpToPage=2

ex:

6). Lastly, enable the "Send on Edit" in autoresponse so you will receive an email after they submitted the form on the second time.

How do you add the submit button even with next?

I figured out how to add the submit button but I don't want a submit button next to "next" so I am kind of confused.

You can hide the Next button Page Break on the first page of your form.

And then, add another submit button on your form and label it as "Next".

Now, after you follow the instructions my colleague, Jed_C, has provided above, when your respondents fill out the first page of your form and hit the Next (which is actually a submit button), they will be redirected back to your form in the edit mode of their initial submission and continue filling out your form again starting on Page 2.

Here's a test form, that you may also clone in your account so you could test it.

Here's what will happen when a respondent submits your form using the Submit button on Page 1.

1. You will already receive the submitted data in the fields on page 1 of your form.
2. Your respondents will be redirected back to their submission in edit mode and continue automatically on Page 2.
