Switch arrows & cast spell

Hiho brothers, i got a problem here, that i can't solve, i searched in all forum and found only one script to use, but it don't worked here, so i tryed myself and got stuck with this mess:

I'm trying to use Diamond Arrow when possible and if diamond arrow = 0, change to burst arrow, if diamond arrow >= x, then switch back to diamond arrow.

So the script have to cast exevo gran con hur when possible (if i use cancast it try to cast everytime even with cd) and equip/unequip arrows dependent on the condition i said b4.


I got this far and it's not working 100%:

Code:

---

auto(100)if itemcount("burst arrow", "backpack") >= 1
then
    if itemcount(25757, "backpack") == 0
    then
        equipitem("burst arrow", "belt", 100)
        waitping()
    end
end
if itemcount(25757, "backpack") >= 200
    then
        equipitem(25757, "belt", 100)
        waitping()
end

---

and to cast exevo gran con hur it's simple and kind of working:

Code:

---

local spell = 'exevo gran con hur'    --Spell to uselocal cap = 200                  -- Minimium amount cap to cast spell
local soul = 3                    -- Minimium Soul Points
local mppc = 20                  -- Mana % to cast.
--## DO NOT EDIT BELOW ##--
auto(30000)
if $mppc >= mppc and $soul >= soul and $cap >= cap and cancast(spell) then
    cast(spell)
    wait(200,500)
end

---

the first one, sometimes changes the arrow for burst even with large amount of diamonds arrows on bp and don't change back, so i have to do it manually.

auto(100)


if itemcount(25757, "backpack") >= 200
then
equipitem(25757, "belt", 100)
waitping()
else
end

tryed like this, and it doesn't equip the arrows, but if i change this equipitem("burst arrow", "belt", 100) then it equip the burst arrow, idk, maybe bugs.
