If you truly are talking about tables in two separates databases the first thing you have to do (as Graham and I mentioned) is to link the databases. Decide which database is going to be your primary database then go to File, Get External Data, Link Tables. Let us know if you need more help there.
Secondly, go to the query window and select "create a query in design view". Choose Update Query from the Query menu. In the QBE (query by example) grid, enter the fields you want to copy. If the field names in the other database table are the same the Update To field will be filled in automatically; otherwise, you'll have to type it in.

By the way, since you're new to this, let me offer you a tip that I wish someone had told me years ago. It's a good idea not to use spaces or special characters (like dashes) in your table, field, etc. names. If you ever decide to start automating your database with VBA (which you probably will) it's a pain in the ... to work with spaces/special characters. Save yourself some future heartache.
