I have a register form where the user can select the type of registration, for example, 'Solo Artist' and 'Band', when the user select one of them the register form is loaded ('Register' button is at bottom of the form) via ajax and centered in the page, if the user want to change his registration type I need to reload the page, but is not very convenient so I thought in a 'Refresh/Back' float button in the right side of the form to remove the current form and load the original select type registration form without load the page, is just a show and hide actions.
My question is: How should it look? Should say 'Back' or 'Refresh'? What about an icon? and the most importante Where should I put it?
Thanks in advance :)
