Unexpacted Token in SendGrid Code

OK, the email is now formatted, and the checkbox data is once again displayed in the body of the email.

I just can’t figure out how to get the checkbox data to appear on separate lines. Something with the template literal I don’t understand. You could always “cheat” and just separate the checkbox data with commas. For example:
Intérêts: Articles, Etaiement, Passerelle

I’ve closed the editor so you can go back in without me being in the way.
