LCD not quite working

Here is my LCD. http://www.sparkfun.com/commerce/product_info.php?products_id=709. The backlight is working, which isnt much. The problem is that it just isnt displaying the messages. The code is the code in the example and i am very certain it is right. The pins are in the same pins as the code and the example shows. So assuming that this is connected right, i think i may know some of the problem.

Could the 6v i supplied have fried it?

it isnt being supplied by the arduino but a seperate battery pack that isnt supplying the arduino, is this a problem?

You should power the LCD
You should power the LCD directly from the Arduino +5V pin. Also, give us a link to the example you’re using.
