This is wrong on multiple counts.
First, isDefined takes a string. Ie, you should do:
<cfif isDefined("variable")>
#variable#
</cfif>
If youdo, isDefined(#variable#) you are saying, "If variable is foo,
tell me if I have a variable called foo." What you really want is "Tell
me if I have a variable called variable.
