I would like to have a formula field that will check if the File Field is blank or not. Below is the formula. It validates, however, it does not work as expected.
CASE WHEN [@field:Images] IS NULL THEN 'No image attached' ELSE 'Image available' END
I used this format in other field like Text(255) and I am getting the expected output. I am wondering why it does not work in File DataType.
Can you please help me?
Thanks in advance!
