Use of ParameterExists
The ParameterExists function has been deprecated since CF4, use IsDefined("var") instead

Type: deprecated
Severity: (3)

Incorrect example
<cfif ParameterExists(>
 do something


<cfif IsDefined("")>
 do something

Deprecated functions may not be supported in future versions of ColdFusion, you should remove them so you can upgrade without worry. The IsDefined function is also faster than ParameterExists.
