I have had a form for the last few weeks that worked exactly as expected. Today the linked fields in the form cannot be clicked to select from the list of linked records. All the field settings in the underlying table and in the form itself appear correct. I even tried creating a completely new form and the problem persists. Here's a link to the live form:

Any ideas what's happening?
EDITED TO ADD: I can add a new record directly into the underlying table with no issues - all fields work exactly as expected!
