This code is not creating the effects . When I pull the table values returns 7 equal positions but were to be different . Help me, please

local distancia_teleport7 = 7
local efeito_teleport7 = 12


function onCastSpell(cid, var)
    local teleport_pos7 = getPosByDir(getCreaturePosition(cid), getCreatureLookDirection(cid), distancia_teleport7)
    local player_pos_inicial = getCreaturePosition(cid)
    if player_pos_inicial.x ~= teleport_pos7.x then
        if player_pos_inicial.x < teleport_pos7.x then
            soma = 1
        else
            soma = -1
        end
    for i=1,distancia_teleport7 do
        player_pos_inicial.x = player_pos_inicial.x + soma
        if isWalkable(player_pos_inicial) then
            table.insert(tabela_pos_ok,player_pos_inicial)
        else
            break
        end
    end
    elseif player_pos_inicial.y ~= teleport_pos7.y then
        if player_pos_inicial.y < teleport_pos7.y then
            soma = 1
        else
            soma = -1
        end
    for i=1,distancia_teleport7 do
        player_pos_inicial.y = player_pos_inicial.y + soma
        if isWalkable(player_pos_inicial) then
            table.insert(tabela_pos_ok,player_pos_inicial)
        else
            break
        end
    end
    end
    for i = 1,#tabela_pos_ok do   
        doSendMagicEffect(tabela_pos_ok[i], efeito_teleport7)
    end
    doTeleportThing(cid, tabela_pos_ok[#tabela_pos_ok])
    return true
end
