Amount of entities in certain range

Hey, I am trying to make a skript where if the players is wearing armor that contains the lore "&7Fear Aura I" it will increase your damage by 10% for each entity in range of the player. But the one problem is I don't know how find out how many entities are in range of the player, everything else is working, but line 6 has an error

on damage:
    attacker is a player
    victim is a player
    if lore of attacker's helmet contains "&7Fear Aura I":
        loop all entities in radius 5 of attacker:
            for each entity in radius 5 of attacker:
                increase damage by 10%

on damage:
  if attacker is a player:
    victim is a player
    if lore of attacker's helmet contains "&7Fear Aura I":
      loop all entities in radius 5 of attacker:
      add 1 to {_entity}
    set {_d} to {_entity} * 10
    increase damage by {_d}%

    increase damage by {_d}%

'{_d} can't be added to the damage because the former is not a number'

Nevermind, I got it

on damage:
  if attacker is a player:
    victim is a player
    if lore of attacker's helmet contains "&7Fear Aura I":
      loop all entities in radius 5 of attacker:
        add 1 to {_entity}
        set {_d} to {_entity} * 50%
        increase damage by {_d}

Thanks!
