accordion menu error 1010 - actionscript-3

Question

I'm trying to create an accordion menu off of an online tutorial. I followed every step (i think) on Original Tutorial but changed things according to my size, as well as make the instance names end with _mc or _txt accordingly. But for some reason it doesn't seem to be working.
I'm getting the #1010 error and it doesn't really clarify anything:
TypeError: Error #1010: A term is
undefined and has no properties.

I have my first xml file that has all the images to insert and that one hasn't been changed at all should work fine.
I know this is long, but I'm hoping someone can check it out anyhow. I'm extremely new to this and would pretty much have to abandon the whole project. Thanks so much!
my code:

"term" refers to an identifier, "Error #1010: A term is undefined and has no properties" means you are using an expression which cannot be evaluated. This usually happens when you try to access and use an undefined object property via its string name as in myobject["property"].method(). Can you provide the exact line on which the exception is raised?
