I would like to calculate a date (or a number of days) - out of 2 givens;
-two possible selections (14, or 7 days).
I want in the end to have FM Pro to tell me what number in a period this date has.
There are 6 periods. Each 14 days or 7 days long. (hence the selection).
I want FM to tell me "you are in period 4" if 58 days have past since the starting date. (4*14 + 2 days) (using the 14 days selection).
What function do I need to use?
