Product multi option quantity problem

Hello, I'm trying to make product option table that change my original checkbox option. I did almost everything but I have problem with quantity part... Does anyone know what I have to do to replace checkbox with quantity text box that they work ? Im trying to modify product.twig and product.php but I cant reach the result.. I'm using opencart 3.0.3.3 with default template. That's my modify untill now:

Something like that would probably only be handled in the commercial Forum Section,
it surpasses free advise by far. Good Luck!
