I have intentionally resigned from further discussions because you did not care to implement. I understood your target long time ago and gave you a perfect solution over Opencart. In above, I have repeated it to make it clear.
If you followed my instructioins, you would have achieved exactly what you wanted to.
With the solution you have applied is something that should not be done. But everyone has their choices to make. If you feel happy with that, that is fine with me.
