Javascript help! I'm so close, but I cannot get checks to work other than checking if it is blank. I need it to also check if the phone number is valid, the email, and the arrival date.

In this exercise, youll develop a Web application that stores data in session storage. The interface looks like this (this interface has been provided to you in the index.html file -- be sure to rename this file and follow the required course naming conventions):

Then, when you click on the Submit Reservation button, a new page gets the data from session storage and displays it like this:

HTML code:
