you don't need the de() call around the variable name, just put it in
quotes:
iif(structKeyExists(struct, "keyname"), "struct.keyname", de("no key"))
Your code was trying to output a variable with a name equal to the value
stored in #struct.keyname#, which isn't what you wanted.
Usually, using CFIF is more readable (especially with complex expressions)
and it's always faster, as it doesn't require any delayed evaluation (which
is slow). Sometimes it's the only way to get a job done, but you generally
shouldn't use it unless you have to.
