Roland, once again you have shone the light on my erred ways. ;^) <cop-out>You see, it's just that I have this chick from admissions that keeps bugging me with her requests and I don't have time to think clearly today.</cop-out>

"Any" appears better than "String" for those values. "Any" seems more ambiguous which is >exactly what form data is. I disagree - Any is far _too_ ambiguous. Also, as far as ambiguity, all values in a user-submitted FORM struct are cast as simple types (strings). Allowing the use of "Any" opens up your code to all kinds of scary validation errors. I could pass in an array, a Struct, a java object, a COM object, or a CFC if I wanted to. In fact, if I was just looking at the signature for your code, I might think that I _could_ pass in any of those, since Any allows that. That's a contract violation. Even if your validation routine checks IsDate() or IsString() (or something to that effect), what's the point of allowing objects to be passed in the first place then? I would always use the most restrictive type that can be allowed for these types of validation routines. In this case, that is a string. All dates can be represented by a string - especially in CF.
