Thanks, Charlie! That gives me the correct output. Now I can move on to the AJAX, JSON, and CF CFC processing of data.
Would you be so kind as to actually explain what function the "i" and "o" play in "function(i,o)" ? They're variables/values passed into the function, right? I tested their necessity by taking them out of your code and just using function() instead of function(i,o) and the code still ran the same. And even some of the example code I found performing this kind of functionality for lists used both i and o in the (), but only referenced the "o" in the actual function. I've always been confused about the role these variables playing in function(i,o) and whatever was in the (). Does the first argument (in this case, "i") always mean something specific because it's in the first argument position? And the same with the variable that's in the second position? I scoured the Internet trying to get a good explanation of using these arguments, but haven't found what I needed to understand. Thanks for any insight you'd share!
