How can I count every next each other checked checkbox in excel?

I'm looking for more then 8h, unsuccessfully. Here is my problem: I would like to count checked checkbox in excel with pause... so count every next each other checked box. For example how many checked checkbox is in group A, and B and .... but group A and B is in the same row (but separated) (it's possible to one row, 19, will fully with checked checkbox). I see the =COUNTIF and another formula can count all in one... but not with separate. Can you offer and help me?

I try wto solve this problem with IF COUNTIF COUNTIFS excel's forms but I can't fixed it.
