Script printing off "12" before I even get to input

total = 0
file = read()

function Clear()
term.clear()
term.setCursorPos(1,1)
end

local h = fs.open(file, "r")
clear()
function Print()
  if not line then
    if total < 15 then
      local line = h:readLine()
      print(line)
      total = total+1
      line = nil
      Print()
    elseif total == 15 then
      sleep(1)
      event,param1 = os.pullEvent()
      if event == "key" and param1 == 57 then
        total = 0
        clear()
        Print()
      end
    end
  elseif line then
    break
  end
end
h:close()
