Hi, Yeah we believe the issue is referencing the same UO dynamic array on the same line.
We have also sent this off to Rocket and are waiting their response. We have fixed the issue as you said by assigning the Val function to a variable first. It's just a little scary to think of the millions of lines of code in our application and what other conditional statement may not be calculating correctly. This means we are having to do a search and replace to find all instances where we are doing a Val in a conditional statement.

Assign your Val functions to variables first and then use these variables in your case statement.
