Can you attach a sample report based on a flat file or classic models data source that reproduces this issue?
 
Clearly, there is a null value happening somewhere but without being able to see the scripting and reproduce the issue it is going to be hard to determine the cause.

Sorry, my Bad. I was looking at wrong datasets.
Out of tow records, val was returning null from database for one record.

I'm glad to hear to you got it figured out.
Thank you for following up with the details of your solution.
