Hi Gowtham,
You are missing the Filter condition in the GetCartoonImageById Aggregate Filter section in the ShowDetails Screen
- Define an input parameter to the ShowDetails Screen called CartoonImageId and refer the same in the Aggregate filter condition as shown below
Filter Condition:
CartoonImage.Id = CartoonImageId


Refer to the attached oml file
I hope this helps you!
Kind regards,
Benjith Sam
