Problem:
The customer reported that the custom code linked to the 'cred_save_data' hook is not working correctly to get the custom field values from the related parent post and set them in the newly created post's title.
Also, the shortcode to include the custom field values from the related parent post in the form's email notification is also not working.
Solution:
After troubleshooting, suggested some changes in the custom function and the shortcodes for the related parent's custom field values.
