When you design a query, you can't just throw tables into the query designer and expect Access to know exactly how you want them joined. You can use the Relationships form to let it know ahead of time what the relationship should be, but you still had to give it that information.
Now think of each of your queries as a table. You can't just throw queries into a report and expect it to know how to relate the information from various queries together.
You should create a single query that has all the information you need. If it's not possible to extract the data from a single query, then you can include that query INSIDE another query. Then give the top level query to the report.
