I want to create a "wizard" like ux in wixsite.
I want to have a "next" button appear (or be clickable) only once a user has finished entering his data in a page containing an iframe with an embedded google form in it (i.e. the user pressed the 'submit' button in the google form).
This 'next' button is linked to a different page in the site showing user date (data from a database in the wix site).
How can i do this?
