Cooldown message fix

[Vic]

Heyy! I just wrote a code which makes a specific item shoot a wither skull, and I wanted to add a cooldown message, but when I try it it just returns with "In cooldown for <none> seconds, here's the code.

on rightclick holding wither rose:
    if player is holding a wither rose named "&c&lSKULLSHOOTER":
        if  {wither.%player's uuid%}  < 1:
            shoot wither skull at speed 1
            add 1 to {wither.%player's uuid%}
            set {_cooldown} to difference between {withercd.%player's uuid%} and now
            play sound "entity.wither.shoot" with volume 0.5 to the player
            wait 2 seconds
            send action bar "&2&lReady to use!" to player
            play sound "entity.experience_orb.pickup" with volume 0.5 to the player
            set {wither.%player's uuid%} to 0
        else:
            send action bar "&c&lIn cooldown for %difference between 2 seconds and {_cooldown}% seconds." to player

every second in "world":
 loop all players:
  if {%loop-player%.withercool} is more than 0:
   remove 1 from {%loop-player%.whitercool}

on right click:
 if player's held item is slimeball named "Skull Shooter":
  if {%player%.withercool} is more than 0:
   send "You still have to wait %{%player%.withercool}% seconds to use that!"
  if {%player%.withercool} is 0:
   shoot wither skull at speed 1
   play sound "entity.wither.shoot" with volume 0.5 to the player

Try this
