I'm new to php, but I've been working around a php form code I got off the net, and I want to know how I can make it so that after submitting, when the thank you message is shown, that the input fields will keep the information that the visitor has just typed in. I plan to change the "Thank You" message into a "Step 2" message, and would like to keep the visitor's information below for them.
Here is the code. It is long, but what I am asking (presumably) is simple.
<?php
//start session
session_start();
