LCD Keypad Shield – Entering and Storing Numbers

So the "value" print right with Serial.print but when I try to print it to LCD the value is now 0000

Gee, I wonder why...

      Serial.print("Saved value: ");
      Serial.println(value);
      strcpy(value,"0000");

Since you step on value as soon as you send it's contents to the serial port, what happens with the contents of value next is NOT a mystery.
