REGISTRATION FORM 1. The student when registering puts his email

FORM 2. I make a record and the date to call the student when his class is due.

WORKFLOW in FORM 2: The notification comes only by putting the Email field.

Question: How do I make the Email RECORD of form 1 duplicate in form 2? And don't do a second manual registration.

I already tried a lookup, subform, but it doesn't work. It only works with an Email Field.

Thanks
