I am assembling the LRTimelapse Pro Timer. I am only part way through the assembly but have encounted a problem. I have installed the sketch onto the Arduino and the display lights up as expected. However the down button does not work so I can only increase the interval ,not decrease it. The leftmost button does nothing, nor does the left button. If I keep pressing the right button and after a few clicks I get PAUSE<Continue and only get out of this by pressing the reset button which works.
Please could you explain what has gone wrong

.. that's an old problem. There are different dispay shields.
Select the alternative display in LDC_Keypad_Reader.cpp and it will work !!

#include "Arduino.h"
#include "LCD_Keypad_Reader.h"

static int DEFAULT_KEY_PIN = 0;

//#define _display_standard_
#define _display_alternative1_

Now perfect. Thank you Sheeba
