Lua Magic wall

[Sigoles]

I wanted to get the name of who attacked while giving magicwall look. tried:

local combat = Combat()
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)
combat:setParameter(COMBAT_PARAM_CREATEITEM, ITEM_MAGICWALL)
combat:setDescription(string.format("Rune thrown by:", creature:getName()))

function onCastSpell(creature, variant, isHotkey)
    return combat:execute(creature, variant)
end

tfs 1.2

Wouldn't you just move it inside the onCastSpell, so it knows what creature is?
Maybe I'm under thinking this though..

local combat = Combat()
combat:setParameter(COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)
combat:setParameter(COMBAT_PARAM_CREATEITEM, ITEM_MAGICWALL)

function onCastSpell(creature, variant, isHotkey)
    combat:setDescription(string.format("Rune thrown by:", creature:getName()))
    return combat:execute(creature, variant)
end

    return combat:execute(creature, variant)
end

we got an error:
