Lua Function error in zombie event.

Description:
data/lib/032-position.lua:2: attempt to index global 'position' (a nil value)

Event works fine, but monsters can't attack players. They attack and deal 0 dmg.

Its something wrong with it?

function isInRange(pos, fromPosition, toPosition)
        return (position.x >= fromPosition.x and position.y >= fromPosition.y and position.z >= fromPosition.z and position.x <= toPosition.x and position.y <= toPosition.y and position.z <= toPosition.z)
end

Whats the correct positions to use in this function?

isInRange(getThingPosition(target), ZE_spawnFromPosition, ZE_spawnToPosition)

Where

ZE_spawnFromPosition = {x = 745, y = 1085, z = 7}
ZE_spawnToPosition = {x = 781, y = 1108, z = 7}

Does not work.
I think i need to change pos near function isInRange, but i dont know how it have to looks like. Someone help?

@EDIT
Ok my error is solved. I have change method. Changed isInRange to getPlayerStorageValue. Changing on enter and on attack(when exit). And it works.

I still dont know how to use isInRange, so can anyone help?

function isInRange(pos, fromPosition, toPosition)
        return (position.x >= fromPosition.x and position.y >= fromPosition.y and position.z >= fromPosition.z and position.x <= toPosition.x and position.y <= toPosition.y and position.z <= toPosition.z)
end

change "pos" to "position" if you're not sure, here it is how it's done (see the highlighted part):

function isInRange([b][color="red"]position[/color][/b], fromPosition, toPosition)
        return (position.x >= fromPosition.x and position.y >= fromPosition.y and position.z >= fromPosition.z and position.x <= toPosition.x and position.y <= toPosition.y and position.z <= toPosition.z)
end
