I will watch the video. I am sure it will enlighten me more I have already rewritten the actual game sheet CF for all the coloring of the cells. I have a feeling doing the rest may be a nightmare lol. If I do not understand how a letter like E takes away certain numbers to begin with I can not re write the logic... although, I have the charts in hand what numbers to take away with certain number groups. The part I need to understand better is the absolute and relative references in the formula as you stated above. Eventually I will figure it out as I get better (-: Again, thanks for your help
