Counting Checkboxes with different Names

Question

I have a form that I am creating in Livecycle Designer 8.0 that has 100 checkboxes that the user selects from. I would like to have a field that counts how many check boxes are checked. What is the easiest way to do this?
Also, Do I have to add each field individually or is there a way to select them all and insert to the formula at once?
Thanks!

Big thanks out to Paul Guerette for helping me write the script for this. He gave me an option to do it as an exit event of the pages or on a button click. Here is the code for the button click:
- form1.Order_Page.Button1::click: - (JavaScript, client) ---
form1.Order_Page.Product_Table.Row3.Course_Quantity.rawValue = 0;
//app.alert("Page1 Exit Event fired!!!!");
//Get total number of element on Page 1 of the form
var allChildElements = form1.Course_Selection_Subform1.Course_Selection_Page_1.nodes;
var intNumElements = allChildElements.length;
//app.alert("The number of elements is: " + intNumElements);
//Loop through all the objects on Page1
for(j=0; j< intNumElements;j++){
//set the 1st object to a variable name
currentElement = allChildElements.item(j);
//if the object is a field then test to see if it is a checkbox
if(currentElement.className == "field") {
//app.alert(currentElement.ui.oneOfChild.className);
// is it a checkbox?
if (currentElement.ui.oneOfChild.className == "checkButton"){
//Is the checkbox checked?
if (currentElement.rawValue == "1"){
//increment the Course_Quantity field
form1.Order_Page.Product_Table.Row3.Course_Quantity.rawValue = form1.Order_Page.Product_Table.Row3.Course_Quantity.rawValue + 1;
//app.alert("Page2 Exit Event fired!!!!");
//Get total number of element on Page 1 of the form
var allChildElements = form1.Course_Selection_Subform2.Course_Selection_Page_2.nodes;
var intNumElements = allChildElements.length;
//app.alert("The number of elements is: " + intNumElements);
//Loop through all the objects on Page1
for(j=0; j< intNumElements;j++){
//set the 1st object to a variable name
currentElement = allChildElements.item(j);
//if the object is a field then test to see if it is a checkbox
if(currentElement.className == "field") {
//app.alert(currentElement.ui.oneOfChild.className);
// is it a checkbox?
if (currentElement.ui.oneOfChild.className == "checkButton"){
//Is the checkbox checked?
if (currentElement.rawValue == "1"){
//increment the Course_Quantity field
form1.Order_Page.Product_Table.Row3.Course_Quantity.rawValue = form1.Order_Page.Product_Table.Row3.Course_Quantity.rawValue + 1;
