Navigator wont show next records

Hi All

Can some one help me on a problem that has just started?

I have a form attached to a number of tables showing fields from two tables
and a {*word*217}y.  The tables are linked on  "one to many", which worked great,
I could navigate using the DBNavigator no problem.

I then changed some of the table fields, and changed the the appropriate
eliments on the forms etc.  Now I can only see the first record of the
table and when I press the navigator control key for next record, it blanks
out, and wont show me any other records.  If I explore the table, it shows
me them.

Any ideas?
