Trouble with Many to Many Relationship

I'm creating a database with 3 tables with many-to-many relationships connecting them.  tblSetup contains information about parts.  tblOperations contains process steps to make the parts.  tblTools contains information on tools used in each operation.  Each part has multiple operations and each operation has multiple tools.  See pic of relationships.

 

In my form I get the attached error message.  I don't understand why I'm getting it or what I need to change to correct it.  Thanks for all your help!
