Success. you picked a class from the site,, picked the calendly button which redirected you to the page test 5. You paid for the class picking one of the 3 options. Paypal redirected you to the page test 4 (right here). If I did this right, calendly should show a missing seat, I should have information and paypal gave you the choice of what class with the correct payment.
More to come such as a confirmation page which some how includes what class you picked, how much you paid, the date, time, etc
