It is best to take web space and domain from a web host in your own country.

Raymond, I have marked your post for Incomedia's attention.

I assume you are using the provided webhosting and simply wish to use your domain name. If required to provide your full address details (and you do not wish them to be public), simply open your first post and  click on the eye to hide the post. We will not see your post, but Incomedia will.

I passed through by typing in 00000000 after trial many times, it works finally.

I have my own domains and work space in my own country. The reason why I want to try to buy a domain via incomedia is only because the other web hosting is very difficult to set up the data base in WebsiteX5, e.g. membership , order management and blog etc. Even when I follow the step of Mr. Aleksius Database section , it does not match the hosting sever easily and it fail at last of course. I just want to test if it will easier to use that domain direct from X5. Since I am not an expert to see inside the PHP... So, it is a good idea if Incomedia will produce some vdo with full step by step instruction for setting up database inside X5 will be perfect, look forwards to seeing that soon. thanks for attention.
