Need help with this in my Database

I am designing a database in Microsoft Access that is designed to help with a small school program. So I have a table which includes all the student info (first name, last name, phone number and Class number) and I made a form (with a tabular format) which includes only the First name, last name, and Class Fields. I want to make this form to be used so that the teacher can use a check box beside each name and add them all to a certain class with a button. This is so that it is much easier than changing the class for each and every student.

THANKS! :eek: :confused:
