Master table not linking to detail table

Overview: 2 tables.  Master with member name and details.  Detail with history of participation.  "msid" is the primary key to Master.  "partid" is primary key to Detail.  Detail has secondary key "msid" which links to Master.  When I run the tables and select a member from the Master, the link fails to the Detail.  

I am attaching Pictures of the Master and Detail SQL sections and a copy of the Trace file when I run the tables.

In your detail table, in the Master link ID field, you reference "jos81_aparticipants.msid", which references the master table.
msid is in fact a field in the detail table, so if you take out the master table reference, and only use "msid" it will work as expected.

As a side note, all fields do not need to be referenced by the table name, you only need to reference the field name
