It is necessary to handle errors during registration so that if a person enters something incorrectly, they are not allowed to proceed further, and at each step, a window should appear indicating success, or if an error occurs, it should be logged.
The form interacts with the CRM system mindbody

Plus two more points
Problem: Registration and user search (CapsLock and spaces)
Essence: User data (names) are stored in the database without processing, with extra spaces and in different cases (for example, "John Smith", " john smith ", "JOHN SMITH").
Consequences: This leads to the system being unable to find the client during subsequent searches or logins.
Task: Fix: automatically remove extra spaces from names and convert to a single case (for example, lowercase) before saving to the database.
2. Problem: Errors when filling out the form (Credit Card)
Essence: If the user makes a mistake in the credit card data, all the information entered in the long form is not saved, but the user does not find out about it (sees a success message).
Consequences: Clients (for example, Leah Yates) spend time filling out the form multiple times and leave disappointed.
Task: Implement step-by-step client-side validation. Do not allow the user to proceed to the next step until the current step is filled out correctly. Show clear error messages under each field (incorrect email, invalid card number, etc.).
