im now doing a booking page, i have to key in the username and the course code. However im not sure how to filter it until the same user is not able to select the same course code with the same username for the second time. I tried “Check new username” and make sure the user do not get to select the code with the same username but by doing this, it restrict the user to only 1 booking. So anyone is able to solve my problem?
