Amigo @gabrielrafaeln buenas. Congratulations you almost made it, I told you that you need to use levels in your node, try to activate both parameters tag and value to work in level 2 (@2), I haven’t tried it yet, but i think will work, I still don’t know how to use levels 100 % but once you understand it you are on the other side, good luck!
