How can I update the 'form.send' function in Streamline?

Hello!

I am very amateur coder and I have worked on creating my own custom fields for a contact form. All the fields are displaying correctly, but the “form.send” function is still tied to my original contact form and is only submitting the fields that form had. Where does form.send root back to?
