Summing Values

[Daniel]

Of course a Boolean is not a number. For binary use such script.

Code:

function tag_sum(tag)
  local objects, result

  result = 0
  objects = grp.tag(tag)

  for _, object in ipairs(objects) do
    if object.data then
    result = result + 1
    end 
  end

  return result
end



sum=tag_sum('Supply'))


grp.checkwrite('1/1/1', sum)
