ERROR check if a date set entered violates a previously entered date set
I am devloping an Excel program that has a list of date sets, not
necessarily in sequencial order. What I want is an ERROR CHECK if a date set violates any date set previously entered. What I was looking for was that a date set could not be typed in as follows: 1/10/04 to 4/20/04 2/10/04 to 3/20/04 The second date set falls within the first set and should be invalid setting off a message or an alert of an invalid entry. I am interested in making it idiot proof so that one could not enter date sets within or covering dates sets already entered. This one really throws me, Please help. |
