1.12 is no longer supported on this forum.
Please update to a modern version of Minecraft to receive support.
Also, common sense/and actually putting in effort by using the search feature of this site would answer your questions.
That is the reason we lock old threads, because the questions have been answered a thousand times before during the supported lifecycle of that version.
