Thanks a lot - works great so far on a test site... can check out multiple times no problem.

The only problem I encountered is that if when I forgot to set the Zone on the shipping adress - then after getting an error correcting it and then trying to go to the next page I got an error - after a page reload it worked again. Only happened once and I can´t reproduce it.. Again Thanks a lot... I do think Multipage Checkouts are much more user friendly (speaking for myself here)...
