Thanks for reply.

Why am I going to add the Customer Phone field, when I want the customer's email field?

The custom field you've set up is not the same as the customer email field.

 

You can add the email field to the printed invoice, but not the screen version.  Use the layout designer to add it to the printed invoice: When designing the invoice, right click and pick Add | Data Field.  Then select the "Customer Phone" field.
