Thank you Paul, that is very handy, as I just mentioned about this to the controller and he accepted that it would be printed left, right, down, left right etc, so so down then across would be ideal, I'll check out. I was even considering an Access report, as I know that can produce a down then across output, but even more work in that case.
In fact it was that page that got me able to print the output in conditional colour, so thanks again.
