Get an alert for start time and end time is comparing with shop hours opening and closing time

I have a form for storing shop timings.Here first i have to set the hours opening and closing time for the shop.Then after i have a button for adding pickup times which comes a modal for adding pickup timing details . Here i have two input time , one for start time and another for end time . My issue is when i enter these times which is not between the shop hours opening and closing time it also get stored. Instead i need to show an error message when this situation comes.
