Variable ID is undefined. Setting ?id to none

Question

Hi,
I need to set me variables so that when i go to the index.cfm
page the index page diplays. Currently I get this error " Variable
ID is undefined." because I have not defined the variable in the
URL. I want an include file to be displayed in the index.cfm page
when index.cfm?id=saex is called.
Does anyone know how to have these variables in CF and still
able me to display just the index.cfm file. Hope I explained myself
well.
Thanks for your help.

<cfif id IS 'home' >
<cfset url = "test.html">

<cfif id IS 'saex' >
<cfset url = "sa-explorer.html">
</cfif>
<cfif id IS 'ckscope' >
<cfset url = "cape-kscope.html">
</cfif>
