Hey folks, I’ve been stuck on trying to get this ■■■■ thing to work for quite a while now, I just want to display nodes with information about College courses when the user chooses the check boxes, any help would be appreciated, thanks

var search_fields:String;
check_science.checked=false;
check_humanities.checked=false;
check_business.checked=false;
check_hotel.checked=false;
function Results() {
    ElementsToSearch = function () {
        var childElementsToSearch = [];
        if (check_science.checked=true) {
            search_fields="Science";
            childElementsToSearch.push("Points");
            childElementsToSearch.push("Department");
            childElementsToSearch.push("Course_Name");
            childElementsToSearch.push("Message");
        }
        if (check_humanities.checked=true) {
            search_fields = "Humanities";
            childElementsToSearch.push("Points");
