Baz,
I received your response off list and tried to reply but got a mailbox
unavailable error. So, here's my response... sorry rest of the list:
--- START OF RESPONSE ---
It's working for me. Here's the code (I used your examples and added a
couple dumps but the looping is the same):
<cfset listOne = ListToArray("andy,bob,jim,craig,steven")>
<cfset listTwo = ListToArray("bob,jim")>
<cfset listThree = ArrayNew(1)>
<cfdump var="#listOne#">
<cfdump var="#listTwo#">
<cfloop from="1" to="#ArrayLen(listOne)#" step="1" index="i">
<cfset itemFound = 0>
<cfloop from="1" to="#ArrayLen(listTwo)#" step="1" index="j">
<cfif listOne[i] eq listTwo[j]>
<cfset itemFound = 1>
</cfif>
</cfloop>
<cfif NOT itemFound>
<cfset ArrayAppend(listThree,listOne[i])>
<cfoutput>Adding: #listOne[i]#<br /></cfoutput>
</cfif>
</cfloop>
<h3>Here are the contents of listThree:</h3>
<cfdump var="#listThree#">
I set up a test page for you to view the results:
