Just wanted some feedback on my main gui before I submitted my project. I decided to keep it really simple. I created an advanced search box and comboboxes for the exact match searching so that the user doesn't always have to retype the entire name which can be tedious. Error box's pop up for certain errors, such as all those exceptions we're supposed to throw. It also makes sure that you enter a 8 digit user ID when you attempt to book your first record.
