Mike asks an important question, but assuming for the moment the function is
in the same class as playNextSection():
What you're retrieving from the XML is a String. So the line
> stepArray[stepCount]["fnct"](val);
isn't going to call a function. It's going to try to treat a string as a
function... and the main way to do that is via [ ] notation.
I think it's most readable to separate it into two steps:
var functionName:String = stepArray[stepCount]["fnct"];
this[functionName](val); // assuming it's in this class. You may also have
to cast this[functionName] this as a function; can't test right now
