I Keep getting errors when I try to upload

same problem with 25. Im pretty sure its a coding problem. I keep getting "Temp Trigger 1" flash o nthe screen so im gonna assume theres an error in this part of the code.

/** LCD Shield            */
serLCD lcd(13); // use both lines
char buf[5]; //used in conversion of int to char for lcd

int configure = 0; //use select as an on/off for configuring
int showReading = 0; //select which value to modify  0-3
int adc_key_in = 1024; //Start with -1 key value

int adc_key_val[5] = {
  100, 160, 360, 770, 800 }; //Analog values from Keys on keypad shield

/*
int adc_key_val[5] = {
 65, 218, 393, 601,1000};
 */
int NUM_KEYS = 5;
int key= -1;

char trigger_names[4][15] = {   
  "Temp Trigger 1",
  "Temp Trigger 2",
  "Humid Trigger",
  "C02 Trigger" };

/* Set up index value for storing values in eeprom*/
int k=0;
