Trying to create spreadsheet with 12 columns for each month of the year. I want to be able to type in an initial due date for example "01/02/02" and have the remaining formulas fill in as the next month, same day, so first column would be 01/02/02 second would be 02/02/02 3rd column would be 03/02/02, fourth is 04/02/02, etc. Then if I go back and change the initial date all the future dates will change to reflect remaining pmnt months.
