I'm really not sure how to go about this. I'm creating a course booking system and when creating a booking I need to check for current bookings with the same employee and course id's (i.e. the employee is already booked on the course). The query takes the employee and course id's from a form, and is initialised when the 'book' button is pressed. It correctly selects if the person is already booked on the course but I want the query to return a value to the form i.e. if it returns null/false then the booking can be created but if it returns a record/true then the booking already exists and a message box can be displayed.
I'm not sure if I'm going about this the right way, can anyone suggest how this can be done as described above or suggest a better way of doing the task?
