I have a chart that is suppose to calculate spending trends over the course of a year. When a number is entered into cell G5 the cell next to it (I5) reflects that number, this represents the beginning of the year. When information is entered into cell G6, the number represented in cell I6 should be the beginning of a running total for the year, the formula I currently have in cell I6 is =I5+G6. As numbers continue to be entered into the "G" column the numbers in the "I" column should grow, showing me how much I am spending each week. What I can't figure out is how to have the cells in the "I" column remain blank until information is entered into the "G" column that is beside it. Right now, what's happening is when I enter a number into G5, that number get's reflected into all of the I cells down to the end of the year. Not sure if this makes sense, wondered if anyone had any suggestions, thanks very much.
