I am having a hard time with a subform updating the SSN field from the main form which is a continous form. The main form has information about all employees. The subform house all of the required examinations of all employees. The two tables are DBO_employee and Exam_Histry. The relation ship is SSN, although the forms are link on LastName, Firstname, and SSN. I would like have the SSN field on the subform populate with the employee's SSN when a new record is created from the main form, or when a new exam is added to the subform. The LastName and FirstName does populate in the Exam_Histry table.
