Unfortunately I'm on CF8. And I wonder if the ternary operator would be able to handle a dynamic value as the output as with my example. IIF works perfect for exactly the type of example you gave; a simple boolean evaluated to output a simple string. The problem lies in CF apparently evaluating the two outputs before determining if the StruckKey exists.
