The typical linkage is that when you change the JobNbr in the Form, you are usually telling the subform to go look for the subrecords for the NEW JobNbr, not telling them to all CHANGE to the new JobNbr.
So, if you want to alter the key on the records in the subform, you'll need a control on the form that explicitly causes an update query to make the change. I'd have a second control for the new JobNbr, label a command button "Move records to new JobNbr", and have code that ran a query to update from the old to the new, then reset the value of the JobNbr field and blanked out the NewJobNbr field and requeried the subform.
