No exception handling on payment

[lailaghaith]

1- Severity --> Medium

2- Reported by --> Laila Ghaith

3- No exception handling on the payment section, as a user / visitor I don't know when the button is going to be clickable or how to make it clickable and not grayed out.

4- Steps to Produce The Issue:
a. open the booking section in the website
b. after selecting a booking time and whatnot, proceed to the payment section.

5- Expected Result --> In case of an error in what the user has entered, a message should be displayed to inform him of what to correct to proceed with the payment.

The submit button is disabled until correct info are provided. Expiration date is in format (MM / YYYY). You entered 2017 as month which is not valid so the button is disabled. If you enter a valid month the button will be clickable.
