Hi,

I am creating a website for a project where you are able to book driving lessons.

I have created code which (sort of) prevents double booking, however, I'm having a problem.

If there is a booking stored in the DB at 11.30-12.30, if i try to book a lesson from 11-12 it prevents me from doing so, however if I try book from 12-1, it allows me to go ahead with the booking.

The code I am using is...
