Sync Member registration form with Contacts?

@givemeawhisky That worked! Thanks for that!

I realized that my “grade” field is also not syncing. I have it setup as a multiple-selection field with labels and values (see photos).

Right now the respective code is

let grade = $w("#gradeLevel").value;

and

"grade": $w("#gradeLevel").value,

But it does not sync to the contact field with the “grade” custom field I have in Contacts. Is there a different coding setup for a multiple-selection field like this, since it is not a text field?
