The customer clicks "Checkout" to jump to the registration page,
How to modify the code
In case the customer is not logged in
I want it to jump to the "main_page=create_account" page

This problem has been bothering me for a long time, asking for help.

Doesn't the current destination have all of the fields present for someone to create an account if they don't have one and the option to login if they do?

If only show the create account page, what is expected of those that have an account already?

I put a login button on the registration page and don't worry.
Most customers don't have an account number when they place an order.
