[thelist] MySQL Table fields

If you go back to the sample SQL query I gave you:

SELECT     i.ItemID, i.CategoryID [whatever your field names are],
            c.CategoryName
FROM       Items i
INNER JOIN Categories c
         ON i.CategoryID = c.CategoryID
WHERE      i.ItemID = '$II'

you should notice that I gave both tables aliases: i for Items and c for
Categories. Then I prefixed each field name with the alias. In fact, if you
have multiple columns with the same name, you have to do this (or as Rudy
pointed out, just prefix with the table name), or the SQL engine isn't
going to be able to figure out which columns you want.
