That's a job for PHP but the code could get quite complicated. It's common for web forms to check if input boxes have been filled in correctly, but showing the result on the same page is an extra piece of coding because web forms are normally submitted to an email or database.

 

Here's an example with two boxes so you could repeat for four boxes:-

Javascript = before the data is sent to the server

PHP = when the data has been sent.

 

So use javascript to make the interaction better for the user, but use PHP to validate again and if somethings wrong you could display the form again along with let say a somewhat red box telling the user where they didn't fill it out correctly.
