ParameterExists was deprecated starting with CF version 3. Don't use it.
As Max pointed out, you should use IsDefined() instead. A bit of history
from my CF 3.1 Language Reference manual:

"IsDefined is intended to replace the Cold Fusion (sic) 2.0 function
ParameterExists. IsDefined eliminates the need for cumbersome
expressions used to test for the existence of a variable:

IsDefined returns TRUE if the specified variable is found, FALSE if not

So just tuck ParameterExists away and fageddaboudit.
