how to make a procedure only activate if it is targeting a specific mob

i have been trying to make a weapon that when used against a specific mob just removes itself from the inventory but otherwise just does a bunch of silly wacky stuff that i already have working but for some reason whether it be through entity tags or well i guess thats about it for checking for a specific mob but still nothing is working

as seen in the image i also have some test send message thingies and neither of them show up in my chatbox either and i am just so confused like i genuinely have developed a headache over this
