Selling Loot on Hive

[Elder' Mariusz]

Hello guys, can u tell me which script is the best for selling items?
I'm using this one

elseif (labelName == "Seller1") then
setWalkerEnabled(false)
delayWalker(10000)
Self.SayToNpc("hi")
sleep(math.random(800, 1700))
Self.SayToNpc("trade")
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('kollos shell')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Swarmer Antenna')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Compound Eye')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Dung Ball')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Waspoid Wing')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Waspoid Claw')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Crawler Head Plating')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Grasshopper Legs')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Calopteryx Cape')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Spitter Nose')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Hive Scythe')
sleep(math.random(1000, 1500))
Self.ShopSellAllItems('Spidris Mandible')
sleep(math.random(1000, 1500))
setWalkerEnabled(true)

but it works good only on 2 characters, on others it's getting bugged and if character doesn't have some item, he's still trying to sell it endless...

can someone help me with that?
