Reach NPC - wait as long as npc is not reachable

Hi. I have problem with buying potions in Farmine. On label "potions" bot is buying potions just when the NPC (Rabaz) is reachable. When Rabaz is not reachable, bot waiting for a few seconds and going away without shopping. How to fix it?
How to do that character will standing near the table as long as he have to reach npc?

Code:

---

        elseif (labelName == "potions") then
                Walker.Stop()
                print([[Shopping]])
                if (Self.ItemCount(ManaPot) < MaxMana) or (Self.ItemCount(HealthPot) < MaxHealth) then
                        Self.SayToNpc({"hi", "flasks", "yes", "yes", "yes", "yes", "yes", "yes", "trade"}, 65)
                        wait(2000)
                        if (Self.ItemCount(ManaPot) < MaxMana) then
                                BuyItems(ManaPot, MaxMana)
                                wait(500)
                                BuyItems(ManaPot, MaxMana)
                                wait(500)
                        end
                        if (Self.ItemCount(HealthPot) < MaxHealth) then
                                BuyItems(HealthPot, MaxHealth)
                                wait(500)
                        end
                        wait(200, 500)
                end
                Walker.Start()

You would make a loop that tries to buy until you have a certain amount of potions.

Code:

---

while(less than potions)
do
  buyPotions
end

Alternatively you can just make the bot go through the door and talk to the npc, or trap him beforehand.
