Check the button with a multimeter. Some switches have 4 pins, and I always use the wrong pins. Check the input of the Arduino with a multimeter, does it change from (almost) 5V to 0V ?
Check if you have selected the right pin number for the button.

It can only be something very simple.
If you don't have a multimeter, try a resistor and led to the 5V at the input. Pressing the button should turn on the led.


It turned out to be the ground was cross patch.  Ugg

Thanks for all of the help!
