I have a similar setup with 3 tables. 1 table with primary key and 2 foreign keys. 2 tables have primary key in each which are foreign key in table 1. I have selected option 2 in the join properties screen. When I run I get the following message. Are you able to identify what I might be doing wrong?
"The SQL statement could not be executed because it contains ambiguous outer joins. To force one of the joins to be performed first, create a separate query that performs the first join and then include that query in your SQL statement."

This is a hard one to explain but this is usually because of the way you're telling access to process the relationship. Imagine our 3 tables are Table A, Table B, Table C. If you do one Join that says include all of table A and only matching in table B, then do a join between B and C that says include all the records. it can't be both.
You can either not make them inner/outer joins (include all where matching rows are equal), or do it so it's A->B->C or A<-B<-C. You can't do something like A->B<-C because some of A->B will not be the same as B<-C, access can't show that information. If you need to do that you need to do a query with A->B and then make a new second query for AB<-C
