Please help me fix this skript, I have been trying for hours

[gamerguy987]

Ok, so im making a skript based on the 3rd life smp and im having problems making a player on their last life be able to start pvp, so a player on their life 1 should be able to start pvp and other players on any life should be able to attack back for 20 seconds,but someone on their 2 and 3 life should not be able to start pvp.

This is what i have now: (This is only the damage section that i need help with)

on damage:
victim is player
attacker is player
if {lives.%attacker%} is 1:
set {can attack.%victim%} to yes
if {can attack.%victim%} is no:
cancel event
if {can attack.%victim%} is yes:
set {can attack.%victim%} to yes
wait 20 seconds
set {can attack.%victim%} to no

In this case someone on their life 1 can attack but people on their 2 and 3 life can't attack back, How do i fix this?

It's a very bad solution but try that

on damage of player:
  if attacker is player:
    if {lives::%attacker%} is 1:
      set {can attack::%victim%} to true
    if {canattack::%victim%} is false:
      cancel event
    if {canattack::%victim%} is true:
      set {canattack::%victim%} to true
      wait 20 seconds
      set {canattack::%victim%} to false
