Thanks Ray. Done the update. There is one last issue and after this one its all complete, sorry for being a pest!
I have created 2 new columns in my eCart object and defined them as Currency, but when showing the cart totals it does not show the "€" symbol neither it forces the result to 2 decimals. I have a few screenshots to ilustrate what i am talking about, i wonder if you could shine some light on this issue... Many thanks again
