Do your push buttons have a pull up (or pull down) resistor?

If not you have to enable the internal pullup resistors on the pushbutton inputs.

I use a pulldown resistor. If I change nothing on the hardware side and use the sample code it works. But not if I integrate the code in to my code.

Please give a description of the symptoms; "stops working" does not mean much.

One thing is that your LCD function blocks your code for a total of 15 seconds; during that time your code will not be able to read the buttons.
