I hope this can be done NEED THE HELP. Counting in binary I have a excel worsheet. Cells a - p are my cells I want the ones and zeros to show up on. In cell Q I want to type a number and the correct 1 or zero will show up in the cells a - p that make that number up. For example if I type a 3 in cell Q I want a one to show up in a and b cells because this makes three in binary. I can emale an example if this will help.
