I'm Trying to make the damage depend on placeholder

[Phoom]

on damage:
attacker's held item's name is "&fPing Sword":
set {_pingg} to placeholder "player_ping"
add %{_pingg}% to damage

I can't do this it shown up as former is not a number how can I set it to number

Is the placeholder a former integer? If yes try

add {_pingg} to final damage

 

[nicolas toledo]

on damage:
  set {_pingg} to placeholder "player_ping"
  set {_pingg} to damage
  increase damage by {_pingg}

 

[Minecoll_YT]

on damage:
  set {_pingg} to placeholder "player_ping"
  set {_pingg} to damage
  increase damage by {_pingg}

I don't think this is what he wants

But I got another idea:

on damage:
  if attacker's held item's name is "&fPing Sword":
    set {_ping} to placeholder "player_ping" parsed as a number
    set {_finaldamage} to final damage + {_ping}
    set final damage to {_finaldamage}
