Troubleshooting custom URL queries to populate forms

edited 05/04/24 in Smartsheet Basics

Here is the base form draft:

Here is the customization attempt (only one query for now) which does not seem to work:

Here is a screenshot showing that the field name matches the one in the query "FirstName"

Why isn't the first name field populating"

I am accessing it from a browser that is not signed into smartsheet as I understand this clears the query. The query still appears on the form in the custom version, but it does not populate to the form.
