Issue about selecting checkboxes

I have a multiple check-boxes and they all are named as numbers.
So all I want is to create is text label, which will include this numbers in total.
Can someone help me with that?

Thanks so much

Hi, I tried something , kinda worked, see file
I am using repeaters and pulling value to checkboxes. Then I make sum using globalVar.
Not sure if it is what you was looking for but you can give it a try anyway
