Subform wants to connect to a deleted table

[Bobp3114]

I have a form with three subforms. all is well except for recent entries in subform frmContactDetailsSubformRF, linked by StationID that says..."you cannot add or change a record because a related record is required in table "tblStationData2".
"tblStationData2" is a table that has been renamed before replacing it with "StationData"
I have rebuilt the subform...no change
There are three main forms similar to this one but covering different sections of business....all are effected!
There has been considerable changes in the database to cover recent changes in freight etc.

maybe the foreign key of this table has been "orphaned" due to your changes.
if you will need major changes, make a Backup first so if any thing goes wrong, like this one,
you can revert to the backup.
