I have created a simple submitting form in PHP at school and run it into XAMPP. It work and there is no error or "notice". but when I got home and run the SAME code with no editing in my XAMPP that I downloaded (XAMPP 1.7.5 beta7) it displayed "Notice: Undefined index .." What could be the PROBLEM? is it the SETTINGS OF XAMPP? or THE CODE ITSELF? help please .. wanting to learn PHP badly! Thanks!
