function onStepIn(cid, item, position, fromPosition)

-- check for monsters  --
starting={x=440, y=971, z=6, stackpos=253}
checking={x=starting.x, y=starting.y, z=starting.z, stackpos=starting.stackpos}
ending={x=456, y=4985, z=6, stackpos=253}
players=0
totalmonsters=0
monster={}
repeat
creature=getThingfromPos(checking)
if creature.itemid > 0 then
if isPlayer(creature.uid) == TRUE then
totalmonsters=totalmonsters-1
end
if isCreature(creature.uid) == TRUE then
totalmonsters=totalmonsters+1
monster[totalmonsters]=creature.uid
end
end
checking.x=checking.x+1
if checking.x>ending.x then
checking.x=starting.x
checking.y=checking.y+1
end
until checking.y>ending.y
-- check for monsters  --

local first_throne = 10000

if item.uid == 10000 and totalmonsters == 0 then
if getPlayerStorageValue(cid, first_throne) <= 0 then


setPlayerStorageValue(cid, first_throne, 1)
doCreatureSay(cid, "The Throne is too powerful for you to sit, you are shaken and absorb part of the spirit of Asmoday.", TALKTYPE_ORANGE_1)

else
doTeleportThing(cid, fromPosition, false)
doCreatureSay(cid, "You have already touched the throne.", TALKTYPE_ORANGE_1)
end
else
doTeleportThing(cid, fromPosition, false)
doCreatureSay(cid, "Asmoday repells you.", TALKTYPE_ORANGE_1)
end
return 1

Post the exact error no this, and wrap the script in code tags.

This error is likely because the coordinates in there are wrong. Look at the first lines.
