Request my Bingo Cards workbook and sneak a look at the code.
VBE project password is provided with the workbook.
I use a two array technique that Tom Ogilvy posted quite a while back.

I am using excel to make bingo cards. I am using the =randbetween(*,*)
formula to generate the numbers but I keep getting duplicate numbers. How can
I ensure that each cell will have a unique number?
