Clear Pathfind Goals of Event-Entity Doesn't Work

[duhnoob1010]

 

For some reason, the "clear pathfind goals of event-entity" does not seem to work for me. 

(I use sQuerry also)

Full Code:

on right click:
    if uncolored name of player's tool is "Zombie Summoner":
        loop all players:
            set {_variable} to loop-players
            if uncolored name of loop-player's tool is "Zombie Summoner":
                if {grey.%player%} is false:
                    message "&4You Can't Do That Yet" to player
                    stop
                    cancel event
                if {grey.%player%} isn't set:
                    set {grey.%player%} to true
                if {grey.%player%} is true:
                    set {grey.%player%} to false
                    spawn a zombie at loop-player's location
                    set {_HM} to last spawned entity
                    set {_ra} to player
                    set name of last spawned entity to "&4Soul Servant"
                    clear pathfind goals of {_HM}
                    loop all mobs in radius 10 around loop-player:
                        if loop-mob is not {_variable}:
                            if loop-mob is not {_HM}:
                                set target of {_HM} to loop-mobs
                                increase max health of {_HM} by 40
                                apply strength 1 to {_HM} for 30 seconds
                                wait 30 seconds
                                set {grey.%player%} to true
                                kill {_HM}
