The easiest way is the isDefined function. It has apparently fallen out of
favor lately, but it will do just fine in this case.
<cfif isDefined("variables.transportation.boat.aluminum.jon")>
<cfset JonIsThere = variables.transportation.boat.aluminum.jon>
<cfelse>
<cfset JonIsThere = 0>
</cfif>

Subject: Correct way to test for nested members
Say I've got a structure of structures:
variables.transportation.boat.aluminum.jon
What's the correct way to test for the the definition of, say, the "jon" var,
if I'm also unsure of the presence of the containing struct(s)?
Thanks,
Jamie
