I didn't actually try running the code, but it looks like the first two of
those CFIF comparisons will evaluate to true, because you're changing the
evaluation conditions for the next CFIF within the previous one. When the
first CFIF sets the cookie, the second CFIF's evaluation condition will
become true. Instead of having three separate CFIFs, why not use CFELSE
and/or CFELSEIF for some of these?
<cfif IsDefined("Form.test")>
<cfif not IsDefined("Cookie.testCookie")>
<cfset searchList = Form.test>
<cfelse>
<cfif ListLen(Cookie.testCookie) lt 6>
<cfset searchList = ListAppend(Cookie.testCookie,
Form.test)>
<cfelse>
<cfset searchList = ListDeleteAt(Cookie.testCookie,
1)>
</cfif>
</cfif>
<cfcookie name="testCookie" value="#searchList#" expires="never">
</cfif>
