Hi Andy;

It has been a long time since i post for the last time, but this time i have to reply about your comment:

Well if you want to complicate a thing ask aa sales man to explain it

Iīm a sales man and what you say itīs true!!!!but it is the way it works. In two weeks iīm having a meeting where i am supossed to be an expert in CO2 world. But I donīt. So i have to study like in university. So i would like people to ask all you can imagine to prepare my meeting, and perhaps in a future i will be an expert in CO2 world

Bye
