James,
I am attaching a CFX tag I wrote that will do what you need. It's called
ListGetChunk and it allows you to extract a portion of a list.
You could use it like this:
<cfset MyList = "23,24,27,30,543,675,980">
<cfset Start = ListFind(MyList, 543) - 1>
<cfset Max = 3>
<cfx_ListGetChunk List="#MyList#" Start="#Start#" Max="#Max#"
NewList="NewList">
<!--- NewList would now contain 30,543,675 --->
<cfset First = ListFirst(NewList)>
<cfset Last = ListLast(NewList)>
Hope that helps,
Chris
