Help with Arduino code

Thanks, Ed. Whish I had someone close that understood this stuff and could explain it to me.
A programming manual is great, but if there's not enough examples to use and try, it doesn't help.
Just spent an hour trying to get the keypad to input a # and display it. I copied the keypad stuff from the sketch in question, as I have that part right, and make it display an input. No go.
