Mac Tahoe 26.5.2
Several years ago I set up a template to reflect monthly cash receipts and cash disbursements. Each month I duplicate that month and then enter information for the new month over the old. The information carries over month-to-month so the final month reflects the annual totals. Recently, a couple of the columns no longer calculate. I have re-entered the formula, but to no avail. The red triangle appears in the 'total' cell and green shading iapears in several cells below.
Help! Please!
