Hi, I followed the tutorial here: Wiring a Character LCD | Character LCDs | Adafruit Learning System
All I am getting is solid white boxes on the top line. Any help would be appreciated. Code is attached, pictures are in this album: Imgur: The magic of the Internet.

Seems that a few of my wires aren't making solid contact with the ports on my UNO.
Your choice of pin numbers does not agree with the introductory comments, but yours make a lot more sense.
Those imported interconnection wires are a frequent problem. Check them out by substituting them, one at a time, for one of the short wires feeding your backlight.
