I ran into this just yesterday. The issue seems to be that since this is a CF function and not a tag it processes it inside out. Not the same as a CFIF where it will skip elements of the if statement should it be false.
The IIF prepares the two DE arguments before it evaluates it's conditional statement. So undefined variables end up throwing errors still even if they should be skipped. I ended up needing to use the CFIF. The CFIF processes faster anyways, but I still try to avoid it when I want to do a conditional statement inside the attributes of an HTML tag to keep the code clean.
