variable declaration?

[milkman]

I am just beginning to learn. I got to the point where I am to call a variable, previously declared in an HTML file form. When I call up the php file, the input does not show up. (For ex: if input="name", then the php file shows upon submission "Welcome, !" without the input). What am I not doing right, keeping in mind that the example I've copied to the letter from the tutorial?
