In this project I created a customized validation for this form's required fields

• Adding customized and conditional behavior.
• Validated user input by providing the user error messeges.

• The activity field after the user selects an activity, other activities with the same day and time are disable to avoid conflicts.
• The credit card number field has a customized error message. It triggers when the user enters dashes in the card numbers. It prompts the user the enter numbers without dashes.
• The following input fields have real time validation

1. name field it must not be empty
2. email field
3. zip Code
4. cvv
5. credit card number
