help Coding

gregv21 (50)
I have a program that prompts the user to put in to dates and then calculates the days the problem is if someone were to put in a / the code would not work properly


i have managed to put in code to make it so the program stops and displays a invalid massage
is it possible to make it so the computer skips write over it and calculates for the numbers anyway


Hears my code:
