I have attached some pics along with an explaination on what pins on the arduino and LCD are linked up and a guide to the connections between the arduino and lcd screen

The aim is to create a 2p change machine as on the youtube link i put up earlier in the thread

The lcd lights up but nothing displays on the screen. The screen should display as on video link below:

relevant section 12.27 - 14.14. I have changed it to show 2p not 10p

So compare and contrast - it should show writing on the lcd but it doesn't show anything.

I don't see the power light lit on the Uno. Is it plugged in?

Adjust the blue pot in the back of the display

In that pic its not plugged in. I'll have a look at the back of the display when im with it later - could it just be a contrast (or similar) issue?
