Thanks Crossroads,
I am going to have to learn what all those commands etc mean. And I thought that building and getting the cube to flash a few lights was challenging. Oh well, this is supposed to be a learning experience so off I go. Thanks again for taking an interest in helping me with this (and many others on this forum) and I will now go off and learn about byte arrayPin, arrayDisplay and "time check in loop" etc.
