Frenzy Script Problem

[perrofunk]

Hi. I'm trying to make a script for auto frenzy. It's useful for instances and 7rb. 

const
frenzy = 176;
var
buff: TL2Buff;
skill: tl2skill;
begin
while delay(500) do begin
   if skilllist.byid(frenzy,skill) and (skill.endtime = 0) and not User.buffs.byid(frenzy,buff) then begin
      Engine.Facecontrol(0, false);
      delay(100);
      Engine.useitem(6314); // homu conversion
      delay(500);
      Engine.useitem(4745); // yaksa mace health
      delay(500);
      Engine.Useskill(176); //frenzy
      delay(1000);
      Engine.Useitem(9443); //my weapon
      delay(100);
      Engine.Facecontrol(0, true);
   end;
end;
end.

Here's the problem. Even if the skill.endtime is not = 0 starts to do the stuff. It tries to use the weapons and frenzy.
