Hi Brian, let me know if it still does not make sense and I will take a look into your script to give you some more specific help.

For stuff like how for( ) loops work in the JavaScript language, there is a pretty good resource here:
http://www.w3schools.com/js/default.asp

That's a bunch of tutorials and reference materials for doing web-page scripting, and that's the same script language that is used by MoI. There are a bunch of tutorials there and some reference materials for how different statements in the language work.
