hello, i am making a hall pass program for my computer programming class. i am having issues with my jcheckboxes. first off. this file reads from a .txt that just has

in it. after the user puts in a correct id number, it displays 4 checkboxes to where they want to go. bathroom, office, nurse, and other. once the user clicks one of the checkboxes, it will remove all the stuff from the panel, and add the name of the person and the time they left. the problem i am having is when the user clicks the checkbox , nothing happens. run this for yourself and see for yourself what happens (if you want of course) this is my final assignment for computer programming and i need help bad lol. i have added an itemlistener, that when the checkbox is selected a boolean = true, then in the actionevents, when the "submit" button is pressed, and the id is correct, and the checkbox boolean is true, it removes all the stuff and puts in all the new elements. i want to say that only the bathroom checkbox has the stuff that it should have to make it work , like added the name and time to the second screen after the 4 checkboxes. also i would like to add that this program compiles just fine, just nothing happens when i click the checkboxes. THANKS IN ADVANCED
