I want to add a column and fill each cell with a unique number starting at 1 and proceeding to end of spread sheet data. I believe this is a "Fill-Series" function. I use to do this at my old job but when I go to "Fill-Series" the series is grayed out. I have treid highlighting the entire column etc with the same result. I must not be addressing this in the correct method. Thank you for your help.
