table relationships and subdatasheets

I'm very new with Access, so I appreciate your patience and help. I created a
database with 4 tables in it and later found that I didn't need one, so I
deleted it. Let's call that Table B. I'm left with Tables A, C, & D. (I had
established a relationship between Table A & B before I deleted it.) Now,
when I attempt to create a subdatasheet in Table A, I get a dialogue box that
says "The table or query name 'Table B' you entered in either the property
sheet or macro is misspelled or refers to a table or query that doesn't
exist." Well, I didn't create a query or a macro. How do I correct this so I
can proceed with the subdatasheets.
