I can't create the joins I want.

If your query has more than two tables, you cannot create outer joins in the query. Outer joins are options 2 and 3 in the Join dialog box.

You can create as many inner joins (option 1 in the Join dialog box) as you want, but you can create only one outer join in each query. If you know how to program in the SQL language, you can try changing the SQL statement in SQL View to create more than one outer join.
