How can I get the passed values to be unique? Rules of this script via the user: Have 4 sections Each section has 8 questions Only 2 out of the 8 questions can be selected in each section Pass the selected questions (checkboxes) to a page where their values (hyperlinks) will be displayed. This code is 95% completed, but I can figure out the rest of this riddle. Any help will be greatly appreciated!!!!
