Thanks for your response.

I changed the fields to a list and that works fine.  Ditto for the 
field.represent feature.  Thanks!

I am still having problems getting the WHERE clause correctly inserted in 
the query.   (The 2-3 different query assignments I originally posted were 
variations I had tried with no luck.)

I would like the query string for a SQLGrid that accomplishes the same as 
the following DAL:

    query = db(db.auth_group.id == PARENT_GROUP_ID).select(
        db.auth_user.last_name, db.auth_user.first_name, db.auth_group.role,
        left = db.auth_user.on(db.auth_user.id==db.auth_membership.user_id
                              
 ).db.auth_membership.on(db.auth_membership.group_id == db.auth_group.id))

The above DAL works fine if I am simply outputting it as HTML.  However, if 
I supply it as a the query parameter to SQLFORM.grid, I get an error from 
the grid.

Ideally I would like to create a SQLFORM.grid that matches the following 
SQL:
Select auth_user.first_name, auth_user.last_name, auth_group.role FROM 
auth_user
LEFT OUTER JOIN auth_membership ON auth_user.id = auth_membership.user_id
LEFT OUTER JOIN auth_group ON auth_membership.group_id = auth_group.id
WHERE auth_group.id = 64; 
 
Any help in pointing out how to get that WHERE clause correctly supplied to 
the SQLFORM.grid is appreciated.
