Wordpress with ACF and Gravity forms, dynamically populate field in Gravity Forms from ACF custom field on page

I have an Advanced Custom Fields (ACF) field called “project_name” in my custom post type “Client.” Each client has a page /client/first-last/. I populate the field within the respective client’s page with the project’s name and then I’m trying to add that dynamically to a hidden gravity form field. I’ve tried shortcode, nothing appears. I can get it to appear in the main page itself with shortcode, but not in the GF field. I’ve tried the custom field option, the ACF field appears there, but nothing ever shows in the field itself. Thanks in advance.
