I'm not sure what you will get from "the value" of a button, but here
is one suggestion:

In your "Go Next Page" button:

on mouseUp
  out 0 into tScore

  repeat with g = 1 to the number of groups
    put the hilitedButtonName of group ("group" & g) into tAnswer
    -- the correct answer (Yes or No) is stored in a custom property
of each group
    put the cCorrectAnswer of grp ("group" & g) into tCorrect
    if tAnswer = tCorrect then
        -- right answer
        add 1 to tScore
    else if tAnswer is not empty then
        -- it will be empty if no button has been selected
        subtract 1 from tScore
     end if
  end repeat

  -- process the results
  answer "Your  score in this section was " & tScore

  go next
end mouseUp

This assumes that every group is a set of answers and that the correct
answer for each group is stores as a custom property of that group
called "cCorrectAnswer".
