How Do I make access to automatically update multiple fields in one table based on the value of a field from another table?

Question

So I have two tables in my database: A : "Daily activities" B : "list of beneficiaries"

A has multiple fields as you can see in the picture: http://i.stack.imgur.com/XMvic.png

likewise, B has its own fields: http://i.stack.imgur.com/9IQ8Y.png

As you can see, both the table share 3 fields together namely, “case_no”, “names” and “nature of case” . now I can assign look up fields that will let me take the values from one table to another, but I don't want that. I want to input the case no in the table A and want the access to automatically fill up the next two fields “name” and “nature of case” by pulling the respective data from its sister table, B based on the value of the given case no. is that possible? If so how can I achieve that? thanks in advance!

thanks to the above tip-off from @Gene, I managed to achieve the results I wanted this whole thing to work in the first place. a little awkward, yes but really helpful. : )
