I'M trying to make my "own" (i read a lot of macros that make the same and take the best for me of each)  autoheal script, but I'm not good at all scripting, my question is why this script doesn't work?

  event macro 24 1
  finditem UUF C_ , #backpackid
  set #lobjectid #findid
  event macro 17
  wait 20
  event macro 37

I'M trying to make my macro disarm drink and arm, but it just disarm and arm 

thank you
