relationship must be on the same number of fields with the same data type

The Jurisdiction column in the Judges table should be a long integer number data type whose value must be one of the values of the autonumber primary key of the Jurisdictions table.  It may be that you have values in the column in the judges table which are not represented in the Jurisdictions table.  You would still be able to create a relationship, but not enforce referential integrity, which would make the relationship pointless of course as it would do nothing to ensure the integrity of the data.  So the first thing to do is check for unmatched Jurisdiction numbers in the Judges

Having a foreign key in Judges does presume that each judge relates to only one jurisdiction, however.  Is that the case or could a judge relate to more than one jurisdiction?  If the latter then you have a many-to-many relationship type between Jurisdictions and Judges.  A many-to-many relationship type is always modelled by a third table, so you'd have tables in outline along these lines:

Jurisdictions
....JurisdictionID (autonumber PK)
....Jurisdiction

Judges
....JudgeID (autonumber PK)
....FirstName
....LastName

And to model the relationship type:

JurisdictionJudges
...JudgeID (long integer number FK)
...JurisdictionID (long integer number FK)

The primary key of the last would be a composite one made up of the two columns.

For data entry you can have a judges form with a subform to enter one or more jurisdictions for each judge, or conversely, a jurisdictions form with a subform to enter one or more judge per jurisdiction. Or indeed both, which gives you the option of entering data either way.   The parent form would be in single form view, the subform in continuous forms view and would include a combo box to select the jurisdiction or judge, set up to show the text value from the referenced table but with the numeric key value as its hidden value.  You'll find an example of this basic form/subform set-up as ParentActivities.zip in my public databases folder at:

The Jurisdiction field in the Judges table should be a Number (Long Integer) field. You can then create a relationship with the AutoNumber field in the Jurisdiction table and enforce referential integrity.

The table will display the numeric key value.

On a form based on the Judges table, you can use a combo box with the following properties:

In the Data tab of the Property Sheet:

• Control Source: the name of the Jurisdiction field in the Judges table.
• Row Source Type: Table/Query.
• Row Source: the name of the Jurisdictions table.

In the Format tab:

• Column Count:2
• Column Widths: 0";1"

The combo box will store the numeric key value, but display the second field from the Jurisdiction table.
