Form with table subform woes

[accessdullard]

I am trying to teach myself MS Access, and I am finding it a very steep learning curve. Currently I am building a vetrinary database for my animals, and want to develop a form that will allow me to view and enter into their vaccination history. I would like to have a seperate drop down on the form, with their names, which will display the table of entries, but only relating to their own entries.
I have reached the end of my very limited skill now, and I wondered if anyone could direct me to the solution?

Gratefull for any advice you can give.

use a query to sort what is related to each animal, then base combo box on that
