Difficulties with Register Helper

Dears, good morning!

As the Register Helper information is directly linked to the meta fields, we replaced the custom information field with a form created in Active Capaign.

The form is great because it gives us all the information back, but how can we make the form button the same as the one that sends the person to the checkout page? Making her click the button just once. It would be a single button with two different versions. We want him to return the form and have him send the same person to the checkout field.

Does anyone know how we can do this? Or if closing the paid service, do we have this option included, or at least an easier way to get the information in the Register Helper? A way that doesn’t depend on coding or php database access.

Thanks.
