subform not showing

[ugly]

Using the access wizard I created a form that shows units, I chose Datasheet view in order that all records could be viewed at once. A unit can have many components - so I included a sub form within my main form that gives visibilty of the components within each unit.
The problem is that when the form is run only the units are showing no sub form is visible -I think this is due to the fact that I have used datasheet view, which I would like to keep - is there any way around this -thanks for any help

This is not possible in the way you have styled it. Have a look at the Customer Orders form in the Northwind sample database, you may find that the idea suits your application.
