Hi again

I have had a play with the code, and have placed the colons in as stated,
I still get no display,

One thing I did find is if I place the Disp1: to Disp4: section into the main loop I get a very
fast flashing faint display,
It does change tho when the i/p pin is toggled.

So I may be getting a little closer.

Any ideas.....?
