Hi All. I've been racking my brain trying to figure this little formula out. I have a bill spreadsheet that I track over the course of a month. I would like to be able to see the balance of the total bill decrease each time I strike through a cell when I receive a confirmation email that it has been deducted or processed. I've tried to write a macro with not luck, and now I'm just looking for a basic deduction formula. I've attached the file and the total is located at C17 and eventually through the month, all of the column C items would be stricken through (see past months as an example). Any help you give will be greatly appreciated. Stretch goal, a macro would be nice, but for the immediate satisfaction, seeing the balance deduct after an item is stricken through would be ecstatic! Thanks in advance.
