Hi acadfdfitness,

Thanks for reaching out to Jotform Support. Unfortunately, our Portuguese Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Portuguese, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. I cloned the form and I was able to successfully submit an entry. You might be wondering how to show the submit button under the collapsable section, right? If that is the case, please see the steps below on how to show it:

1. On the Form Builder, add a new section collapse widget.
2. Click the gear icon to open the settings.
3. Set the Section Visibility to Visible.
4. And then set Button Visibility to Hidden.

Once that is done, you will get this result. See this demo form's screenshot:

Give it a try and reach out to us again if you need more help.
