Since they all have the same name you need to use the elements array to acces them. The elements array holds all of the objects in the form (checkboxes, radiobuttons, text fields, etc).
access it like this:
formName.elements[index];
to see if the item is a checkbox you could test it this way:
if (formName.elements[index].type == "checkbox")
and then just add a test to see if it selected or not:
if (formName.elements[index].type == "checkbox" && formName.elements[index].checked)
if the above line is true then the element is checkbox that is checked.
Loop through all of the elements in the elements array with:
for (var i=0; i < formName.elements.length; i++)
hope that helps

Ok, I can do checkboxes, but what if you have multiple SELECT BOXES with the same name. How do you reference each one's selected value?

Why would you have select boxes with the same name??

I used multiple select boxes with same name. It is very useful in some cases. For example, if the number of select boxes is unknown at development time, and we need to retrieve their values when the page is submitted.
