HD44780 issues

Hi guys,
I've got a HD44780 LCD character Display Module and I'm trying to get it working with Espruino. I've followed the guide here http://www.espruino.com/HD44780 and installed the HD33780 module, but whenever I run the code I get the following error:

// My code
var lcd = require("HD44780").connect(A4,A5,A0,A7,A2,A3);
lcd.print("Hello World!");

// Error returned
>echo(0);

Do you have any idea what's going wrong here? I've tried writing the module code directly but I get much the same results. What should I try next to fix this?
Thanks
