Formula Referring To Empty Cells

I think I understand what you were talking about now with the generation of the watchbill using the rand() and sort. You were trying to get me to get rid of the whole system I was using before and use only the rand and sort. I thought you were asking me to incorperate the rand sort thing into the randomization process I already had using offset etc. The whole thing works good now, however, because the column Ive designated for the roster names may or may not always be filled the formula sometimes refers to empty cells in that column thus producing 0s on the watchbill. I was thinking maybe (if its possible) having a formula to identify a 0 and if so skip to the next cell down. The formula would repeat until it found a name without a zero in it.
