Form/subform setup

Hello!

For a Veterinarian database, I can't seem to get the form/subform
structure working.

Open the form. Enter the date. Then, in a subform below, enter the ID#
of the dogs that showed up that day. (could be one, could be 50). When
you enter the ID, info for that dog can be seen (name, breed,etc.)


Then for the selected dog (another subform?), enter the conditions the
dog has (could be 1, could be 50). (Cough, limp, etc.)
