Webmatrix stuck

[ccd]

as of now, i am stuck at this step 6 of the following
section

http://www.asp.net/webmatrix/tour/section3/formatdatagrid.a
spx

When the Collection Editor dialog box appears, it does not
show like that in the tutorial, it does not show any
BoundField at all.

I check everything and i am sure i did all steps
accordingly.

Is the tutorial kinda out-dated? Some of the pictures
snapshots in the tutorials do not match the real things.
Like when I was working on the Data Tab in the Workspace
window, it showed a different set of icons. The same thing
happened when creating a database. The tutorial does not
mention that I have to choose between Access and SQL
database. So I chose the later. Not to mention the Orders,
OrdersDetail tables. Does it make any difference at all?
So what's database type used in WebMatrix?

Thanks again
