Hey all! I am trying to design a system for our staff to add "points" to users for participating in events. I currently have the following code. The "Edit" and "Update" code works. I have tested it. What is not working is the main "add" part. A staff member should be able to type in multiple usernames separated by a semicolon (

then the correct number of points should be added. If anyone can help, let me know!
