Note that my first statement is *not* 'drivel':
<cfif isDefined("myVar")>
<cfset result = "the value myVar is " & myVar>
<cfelse>
<cfset result = "">
<cfif>
The above works. The following, with iif(), does not:
<cfset result = iif(isDefined("myVar"),"the value myVar is " & myVar,"")>
iif() will evaluate all three arguments first, *then* return either
the 2nd or 3rd argument based on the value of the 1st argument.
