database - ms-access: Why isn't this relationship not working? -


just started today understanding relations between ms access databases. can figure out why isnt working?

i can explain lot in way, think pictures says more 1000 words

tblinfo tblopdr relations tables

when have relationship set up, little plus sign in datasheet (third picture) , when click sign, see records matching relationship field (column). if there no matching records, can add them, indicated asterisk (*)

the plus sign show related records. if have used relational integrity, can add records 'many' table have identical foreign key (matching field) 'one' table. not idea work tables, should use forms. if set form based on 'one' table , add subform based on 'many' table, foreign key filled in automatically (the wizard set link child , master fields you).
