First of all, checkboxes don't have numeric values, so how could they be added? Please explain with more than one vague sentence.
Once you've elaborated on what you are actually trying to do: what have you thought of so far? Have you even tried any code? What's stopping you from progressing?
You'll find that you will get a lot more help here when you put in some effort of your own.
