Scrotter issue

[LeVraiArdox]

Hi there.
i replaced maim with scrot in you scrotter script. But idk why, only the "window" script seems to works.
The "selection" have a problem too: it works only one time on 10.
Is maim very important for the code ? Or am i just shitty ?
here is the snippet:

  local fullscreen = createButton('󰍹', 'Fullscreen', function()
    close()
    local name = getName()
    local cmd = "scrot " .. name
    awful.spawn.easy_async_with_shell(cmd, function()
      copyScrot(name)
    end)
  end, beautiful.green)

  local selection = createButton('󰩭', 'Selection', function()
    close()
    local name = getName()
    local cmd = "scrot -s " .. name
    awful.spawn.easy_async_with_shell(cmd, function()
      copyScrot(name)
    end)
  end, beautiful.blue)

  local window = createButton('󰘔', 'Window', function()
    close()
    local name = getName()
    local cmd = "scrot -u " .. name
    awful.spawn.easy_async_with_shell(cmd, function()
      copyScrot(name)
    end)
  end, beautiful.red)

local getName = function()
  local string = "~/Images/" .. os.date("%d-%m-%Y-%H:%M:%S") .. ".jpg"
  return string
end
