Slowness instead of Fall damage

[Ter2FIc]

I am trying to give player slowness instead of fall damage and I want to make slowness V for fall damage x 3 seconds.

on damage:
    if victim is player:
        if damage was caused by fall:
            set {damage::%player%} to damage
            cancel event
            apply slowness 5 to victim for % {damage::%player%} x 3 % seconds

 

[yea rite]

this should work

on damage of player:
  if damage cause is fall:
    cancel event
    set {_time} to damage * 3
    apply potion of slowness of tier 5 to last victim for {_time} seconds
