Hello, I'm having a little trouble figuring out how to retrieve user inputted data from a form submission. I'm somewhat new to web developing, but learning very quickly. It took me a while, but I finally got my form designed and working the way I would like (including JavaScript for some elements). After reading through w3schools.com I can understand how to display the information to the "user/inputter" with PHP or ASP after they submit, but how do I retrieve that form data and use it myself. My form submission is for a service signup for my business, and I need to retrieve the information in a manner in which I can use to manually or automatically export/import that information to my business (non web) software.

Also, another quick less important question to finish my form design, is how do I display a "verify information" page that displays all the fields inputted by the user so they can check if all the information is correct before they actually submit it?
