LCD-00255 contrast.

After searching the forums, Ive come up short on answers.

I have the [LCD-00255 hooked up on my breadboard with ~4.3v to the backlight via a voltage divider and 5v to Vcc from the power supply strait from the tutorial. The only thing not right is my contrast. Ive got a 1k pot connected to 5v on the left leg, contrast on the middle and gnd on the right. The only time anything shows up is when the pot is all the way right (no resistance to ground), and then its just the top row of blocks and a ghost of the bottom. Ive disconnected the data pins til I figure this out. Anyone know whats wrong?](http://www.sparkfun.com/commerce/product_info.php?products_id=255)
