Sounds like you are using an INNER join and need a LEFT join.
In the design view double click on the line connecting your tables. Select
the option that will display the most records - example - display your master
table and only those of slave that match.
So figure out which table is to be the left most (has the most of the
records of the field you are joining on). An alternate is to use a union
query for a complete list of the field you are using to join and use it as
the left table.
