What I'd like to do is get the last 3 elements from my list, maybe I'd like to get the first 3 or the last 5, etc. Ideally I'd do the following to get the last 3 elements in my list: myList = "1,2,3,4,5,6,7,8,9,10"; Right(myList, 3); This doesn't work as ColdFusion treats a List as a String, so the above will only return the last 3 characters in my list (",10"). I could do the following to get what I need: <cfset myList = "1,2,3,4,5,6,7,8,9,10"> <cfset myNewList = ""> <cfloop from="0" to="2" index="idx"> <cfset myNewList = ListAppend(myNewList, ListGetAt(myList, ListLen(myList) - idx))> </cfloop> But I see this looping and having to work out the correct from/to values a bit messy, there must be an even simpler way, anybody have any tips for me?
