CF Error: Invalid list index 1

[3dColor]

I get a Coldfusion error each time someone (or something) comes to my site with no agent user declared.

CF Error: Invalid list index 1. In function ListGetAt(list, index [, delimiters]), the value of index, 1, is not a valid as the first argument (this list has 0 elements).&nbsp;Valid indexes are in the range 1 through the number of elements in the list. <br>The error occurred on line 17.

This is my code around line 17:

<!--- 301 redirect to [URL unfurl="true"]www version[/URL] of site, cgi.http_host gives you [URL unfurl="true"]www.mydomain.com[/URL] --->
<cfif domain NEQ "[URL unfurl="true"]www.mydomain.com"[/URL] AND NOT ISDEFINED("URL.cs")>
	<!--- set nonwwws to what is possibly a subdomain or ad id --->
    <cfset nonwwws = listGetAt(domain, 1, ".")>
	<cfif nonwwws EQ "rentvine">
		<cfheader statuscode="301" statustext="Moved permanently">
		<cfheader name="Location" value="[URL unfurl="true"]http://www.#widgetURL#/">[/URL]
	</cfif>
</cfif>

Any ideas how to prevent this error?

CF Error: Invalid list index 1.

That suggests "domain" is an empty string. So you must handle that case. You might try using a different CGI variable. See if you get different results.
