Plumsail Forms: Lookup DropDown populates other field upon selection

Dear @CBOI_GGriffin,
Thank you for posting! Unfortunately, the link is a bit misleading, as users were largely asking a question for another product here.

In your case, you can try something like this, and let me know if you face any issues:

fd.spRendered(function() {
  fd.field('Lookup').$on('change', function(value) {
    fd.field('Phone').value = value.CompanyPhone;
  });
});
