     I think here better to use .link(linkName)
    
    because tomorrow you can add more links, and your code
    suddenly will start work wrong

Yes, btw, I know Lingo allow do some classes?

May be even better use classes :-))

    what means here "right value" ?

Have you check after this your db using e.g. Vstudio ?
Are records linked ?

May be send us simple project which do this ?

BY THE WAY!  
    
    Note that in first function you use Link( name )
    but in second link( 1 ).

    May be you already have come into this trap,
    and you use wrong link in fact in second case!!!
