Always post the script not just the error.

ok sorry about that

 

[Linxsis]

Code tags please and could you clean up the indentation? I am sure it doesn't look like that in your script.
See the difference?

local variable = 1

idk what you mean but heres the file

function onCastSpell(creature, variant)

    if creature:getSkull() == SKULL_BLACK then

        creature:sendCancelMessage(RETURNVALUE_NOTPOSSIBLE)

        return false

    end



    local monsterName = variant:getString()

    local monsterType = MonsterType(monsterName)



    if not monsterType then

        creature:sendCancelMessage(RETURNVALUE_NOTPOSSIBLE)

        creature:getPosition():sendMagicEffect(CONST_ME_POFF)

        return false

    end



    if not creature:hasFlag(PlayerFlag_CanSummonAll) then

        if not monsterType:isSummonable() then

            creature:sendCancelMessage(RETURNVALUE_NOTPOSSIBLE)

            creature:getPosition():sendMagicEffect(CONST_ME_POFF)

            return false

        end



        if #creature:getSummons() >= 2 then

            creature:sendCancelMessage("You cannot summon more creatures.")

            creature:getPosition():sendMagicEffect(CONST_ME_POFF)

            return false

        end

    end



    local manaCost = monsterType:getManaCost()

    if creature:getMana() < manaCost and not creature:hasFlag(PlayerFlag_HasInfiniteMana) then

        creature:sendCancelMessage(RETURNVALUE_NOTENOUGHMANA)

        creature:getPosition():sendMagicEffect(CONST_ME_POFF)

        return false

    end



    local position = creature:getPosition()

    local summon = Game.createMonster(monsterName, position, true)

    if not summon then

        creature:sendCancelMessage(RETURNVALUE_NOTENOUGHROOM)

        position:sendMagicEffect(CONST_ME_POFF)

        return false

    end



    creature:addMana(-manaCost)

    creature:addManaSpent(manaCost)

    creature:addSummon(summon)

    position:sendMagicEffect(CONST_ME_MAGIC_BLUE)

    summon:getPosition():sendMagicEffect(CONST_ME_TELEPORT)

    return true
