NodeJS API: having trouble passing 2 parameters to request response - node.js

Question

I am having trouble passing 2 ids via request response function. I can pass 1 id/argument without any issue but having trouble passing 2 arguments below is a snippet of my code:
server:
var http = require("http");
var org = require("../controllers/org");
var school = require("../controllers/school");
var academicSession = require("../controllers/academicSession");
var term = require("../controllers/term");
var gradingperiod = require("../controllers/gradingperiod");
var course = require("../controllers/course");
var stu = require("../controllers/student");
var cls = require("../controllers/class");
var user = require("../controllers/user");
var demo = require("../controllers/demographic");
var enroll = require("../controllers/enrollment");
var teach = require("../controllers/teacher");
var crscls = require("../controllers/schoolcs");
var enr = require("../controllers/enrollqrys");
var settings = require("../settings");
var httpMsgs = require("../core/httpMsgs");
http.createServer(function (req, resp) {
switch (req.method) {
case "GET":
if (req.url === "/") {
httpMsgs.showHome(req, resp);
}
else if (req.url === "/orgs") {
org.getOrgs(req, resp);
}
else if (req.url.match("/orgs/[0-9]+$")) {
var idorg = "[0-9]+";
var patt = new RegExp("/orgs/" + idorg);
if (patt.test(req.url)) {
patt = new RegExp(idorg);
var id = patt.exec(req.url);
org.getOrg(req, resp, id);
}
else {
httpMsgs.show404(req, resp);
}
}
***else if (req.url.match("/schools/[0-9]+[A-Za-z0-9\-\_]+/classes/[0-9]+[A-Za-z0-9\-\_]+/enrollments$")) {
var idcl = "[0-9]+[A-Za-z0-9\-\_]+";
var idsc = "[0-9]+[A-Za-z0-9\-\_]+";
var str = idcl + "[0-9]+[A-Za-z0-9\-\_]+" + idsc;
var patt = new RegExp("/schools/" + idcl + "/classes/" + idsc + "/enrollments");
if (patt.test(req.url)) {
patt = new RegExp(str);
var id = patt.exec(req.url);
enr.getEnrollmentsForClassInSchools(req, resp, id, arg2);
}
else {
httpMsgs.show404(req, resp);
}
}***
enrollqrys.js:
var db = require("../core/db");
var httpMsgs = require("../core/httpMsgs");
exports.getEnrollmentsForClassInSchools = function (req, resp, id, arg2) {
db.executeSql("EXEC dbo.getEnrollmentsForClassInSchools #clid = '" + id + "'" + ", #scid = '" + arg2 + "'", function (data, err) {
if (err) {
httpMsgs.show500(req, resp, err);
}
else {
//resp.writeHead(200, { "Content-Type": "application/json" });
//resp.write(JSON.stringify(data));
//resp.end();
httpMsgs.sendJson(req, resp, data);
}
});
};
exports.getStudentsForClassInSchool = function (req, resp, id, id) {
db.executeSql("EXEC dbo.getEnrollmentsForClassInSchools #clid = '" + clid + "'" + ", #scid =" + scid, function (data, err) {
if (err) {
httpMsgs.show500(req, resp, err);
}
else {
//resp.writeHead(200, { "Content-Type": "application/json" });
//resp.write(JSON.stringify(data));
//resp.end();
httpMsgs.sendJson(req, resp, data);
}
});
};
I get a not referenced error when testing this GET. Any help would be greatly appreciated. I will add that I am new to both javascript and nodejs
