In the attached DB the CR NO is the receipt no. If the same person comes again instead of typing his details they can be got from the record. This is the purpose of the subform. Now, when in a new record we type the LNAME it shows the corresponding records in the subform and when we doble click on the field in the subform it tranfers the corresponding details to the main form. But the problem is that when in a new record we type FNAME it shows corresponding details in the subform but when we double click on the field of the subform it does not transfer the details to the main form.

I have moved your post from the introduction section to the forms section.
