Unless there is some reason the forms need to be linked, I would just use the
wizard to create 11 different forms. Getting into that many subforms not only
get troublesome to link correctly, but gets really unwieldy on space issues.
You don't have enough room on the page for all the stuff going on at once.
Another option is to used tabs and have 11 tabbed forms. The users could
easily switch from tab to tab to get data. That gets a little unwieldy also.
The wizard will create the forms for you better than you could probably
create them yourself, just use it.
