Have a field that holds month names (January thru December) called Base Month. Have a due date field that needs to be the month that is in the month name field. Am using a calculation based on current test date to determine when next test is due (Due Date), but realized, if test was done on following month or previous month (which it could be), the Due Date would show an incorrect Due Date month. How can I incorporate into Due Date the month in the month name field. How this is clear enough.
