How do I add variables to different checkboxes without using the 'Export Value' and then add them together (if checked)?

Question

Hello,
I am very new to JavaScript.  I would like to create a checkbox with a numerical value variable activated if the box is checked.  Unfortunately, I cannot use the 'Export Value' because I already need to use it for something else.
Any help is really appreciated.
Thanks,
Robyn

Brace yourself, here's your solution.
First of all, the export value of you checkboxes should definitly be the number of hours for the class since you will just add them up further.
Second, we will use the userName property for our second export value (its the field right under Name and its labeled "tooltip").  You will name the class there.
Finally, you need to name each checkbox with a number at the end starting with 1 all the way to 190.  This will be used in loops. ("whatever.1", "whatever.2,....."whatever.190")
In the calculate event of "total hours":
var sum = 0;  //declaring a variable that will be used in the loop
for (var i = 1; i <= 190; i++){    //this loop will scan through all your checkboxes
     if (this.getField("whatever."+i).isBoxChecked(0) == true){  //if box is checked....
          sum += Number(this.getField("whatever."+i).value);   //.....add its value to the sum
event.value = sum;  //display the total
Now for the course name field, we will use the same pattern in the calculate event
var courseList = new Array();  //declaring an empty array that will contain the courses
for (var i = 1; i <= 190; i++){    //this loop will scan through all your checkboxes
     if (this.getField("whatever."+i).isBoxChecked(0) == true){  //if box is checked....
          courseList.push(this.getField("whatever."+i).userName);   //.....add its userName (tooltip) to the array
event.value = "You are attending these courses:  "+courseList.join(", ")+".";  //display the array by turning it into a string and joining its items with ", "
You can try it out with just a few checkboxes at first.  Don't forget that the loop mustn't go further than the existing field or you will get an error and the script will stop.  Make sure no error show in the console (ctrl+J).
