If your reply is sarcastic (as it seems - I might be wrong, it is hard to tell on forums) then I would recommend you read the article again.
It might not be what you want to hear, but it is the reality. Lookup columns are a half-assed proprietary Access sack of cack that should be avoided at all costs. Google Dev Ashish (the author of that article) if you doubt his credentials.
I have heard all of the evils of using Lookup columns but I continue to use them anyway. I find them to be very helpful/useful. However, I am my own user. The programs that I write are the programs that I use. So with that said, if you still want to know how to do it then here it is:
Design your table, choose the column you want, click on the Lookup Tab at the bottom of the design screen. Then switch the Display Control to Combo Box. Then a Row Source property will be visible. Click on the ... to go the query designer. Add the table that you want and the fields you want. In most cases you will add the table's Primary key along with a description field. Then close you query and save the changes. Access will put the SQL in the Row Source property.
If you have used two fields (Primary Key field and a description) then Bound Column should be 1 (Access will store the Primary Key but display the Description). Then in the Column Count field put 2 and finally in the Column Widths field oput 0;2 for 0 inches for the first field (effectively making it invisible to the user) and 2 inches for the Description field.
Save and open your table. Then the user can select the description instead of trying to remember that 1 = Fax and 2 = Phone etc.
