[AS2]XML Quiz Array Answers with different Values. Help

[terraform]

I have this project where I have a quiz template that I am using
(as2) and I have everything exactly the way I want it
except....
that I need for the individual questions to hold a different value from one another.

for example
Question 1 = 10 points
Question 2 = 20 points

so on and so forth

right now I have it so they are an equal percentage of the total
(ie 10 questions all are worth 10 points)
and I need to change that

unfortunately I am still teaching myself AS but even more unfortunate for me
is that I am learning AS3 and this template is AS2
I also have not done much in this vein I have been concentrating more on
UI kind of stuff and less on the math side
so if anyone can point me in the right direction I would greatly appreciate it,.
also it makes no difference to me if this is done in AS or XML
this file will not be continually updated so it can be a one time deal

thanks

Ok
well I think I at least have a clue as what needs to be done
but I will admit that I don't have any idea as how to get there.

what I have
I have an as2 xml quiz that does NOT assign a weight (or value) to individual questions.
It instead divides the the correct questions by the total questions and multiplies x100 to achieve the percent total.

what I need
I need to declare a value for each question. (to be assigned in the XML)
I believe I need to create a variable in my as2 code
I believe I need to add an attribute to the child nodes (ie weight)
I believe I need to add a "value" or "weight" attribute to the external XML file
lastly I believe I need some line of math that would add up the "weight" of
each of the individual questions on Quiz completion.

I have tried every variation of this that my feeble mind could come up with
and never with any success.

again array work and xml are all new to me and on top of that I have been attempting AS3 so the differences have been tripping me up further.

I have attached a .as file (it is on the timeline but I figured you don't need the .fla) and the .xml file so you can see it all in its entirety.

thanks to anyone that can help me on this.
