code from tronixlabs for LCD

I have a problem with this code example. It verifies except for the lcd.print() instruction in void loop. Here it declares lcd is not declared in this scope. Ordinarily I would check that I had the correct library installed and that there was no syntax error but I can’t see it. Can someone?

Demonstration sketch for PCF8574T I2C LCD Backpack

include <LiquidCrystal_I2C.h> 
LiquidCrystal_I2C lcd(0x3F,2,1,0,4,5,6,7); // 0x3F is the I2C bus address for an unmodified backpack 
void setup() { 
// activate LCD module 
lcd.begin (16,2); // for 16 x 2 LCD module 
void loop(){ 
lcd.home(); // set cursor to 0,0 
lcd.setCursor (0,1);        // go to start of 2nd line 
lcd.setBacklight(LOW);      // Backlight off 
lcd.setBacklight(HIGH);     // Backlight on 

You don't have the # in front of the includes.

Please re-copy the code from:

Furthermore you need to delete or rename or move the existing LiquidCrystal library then download and install a new one. For more information please visit:
