ValidationException with a defined variable

Content

I'm looking to have a validation exception or warning pop up and visible to the user but I want to include a def variable and not specifically a hard-coded message as seen below. Is this possible in CX Sales 19D. These code snippets in my Functions aren't working for me. Any ideas?

throw new oracle.jbo.ValidationException(‘MESSAGE: ’ + variableName) 

or

throw new oracle.jbo.ValidationException(variableName)
