give the argument a default in the CFC. That way if the variable isn't
passed to the CFC, it wont cause an error. Mind you, if you use it in the
wrong place you wont throw an error, you'll have wrong values in your
function, so be careful where you use it.
<cffunction name="thisfunction" >
<cfargument name="foo" default="thisvalue">
. stuff .
</cffunction>

You could use the Iif function, I guess, but you could also just check for
the variable's existence before your CFINVOKE tag.
