I have a worksheet that needs a timestamp in the cell in the next column to the entry cell - Column N has the cell that requires an entry and Column O has the timestamp (MMM/DD/YYYY H:M:S). That timestamp can't change unless someone updates the cell in Column N, then it gets the new timestamp value. I have developed some VBA code that works perfectly. I am seeking a solution that doesn't need VBA. I know that NOW() and TODAY() won't work "out of the box" because they are dynamic and will update with any change to any cell. Is there a non-VBA solution? Thanks in advance for your insight.
