Javascript, quizzes and you--potentially a cautionary tale. Help!

Question

So one of our trainers set me up with a little challenge and I thought Captivate might do the trick. Our training department spends a lot of time manually grading proof of learning tests, and she wanted to know if it would be possible to have quizzes that are "intelligent" enough to pick up variances in user input and still let them get the answer right.
I set up my quiz as a number of standard slides with captions and text entry boxes, and wrote a small mountain of javascript that uses regular expressions to validate all the question input (for example, a question about current call opening uses a Regex of /((my name(\'s| is)|you(\'re| are) (speaking|talking) (to|with)))\s\w+(,|.|\s)\s?(what(\'s| is)|(may|can) I( please)? (take|have)) your name( please)?\??/i to accept different variations of someone introducing themselves and asking for the caller's name.
The good thing is that after two days of painstaking research, bugfixing, picking through Javascript with a fine-toothed comb, finding out that JS boxes have a character limit, working out a way round it by having filler slides with JS that go to the next slide when the processing is completed, and nearly crying when I finally managed to get 100% on the quiz with the most outlandish correct input I could think of...I finally hit the straw that broke the camel's back.
See, in my Javascript I'm incrementing a variable called "score" whenever the user gets a question right, then at the end of the script adding that variable's value to cpQuizInfoPointsscored. I have a summary slide at the end which displays the value of this variable and it works perfectly.
The problem comes when implementing this wonder-test into my LMS.
Unfortunately, after attempting the quiz, my score remains resolutely reported at a big fat 0 regardless of what my actual score was. I found a forum post by Lilybiri saying that it isn't actually possible to externally manipulate the variables that get sent to SCORM, which essentially makes everything I've done since Tuesday completely and utterly useless.
I'm at my wits' end here, because if I can't salvage this after everything I went through to make it work I am honestly going to go postal. There must be something, anything, some kind of workaround for this that will let me send a custom score to SCORM and report it accurately on the LMS. There must be! Please, for the love of all that you all hold dear, help me with this and I'll love you forever.

Answer 1

The odd thing is though, Lily, that on my summary slide I have a text caption with "Your score: $$cpQuizInfoPointsscored" and it actually displays the correct value that I set it to using cpEISetValue in Javascript. So if its value is actually what it's meant to be (it would just display 0 if the variable manipulations weren't doing anything after all) then why is this not the value that gets sent to SCORM?
The problem with knowing how many points to assign beforehand is that each question has multiple points that it checks for. Like the call opening question gives a point for welcoming the customer to the call, the agent introducing themselves/asking the customer's name, and asking how they can help. My code looks like this:
var objCP = document.Captivate;
var answers = [];
for (i=5;i<9;i++) { answers[i] = objCP.cpEIGetValue('s1_txt_Q' + i); }
calculate_Grade();
function calculate_Grade() {
var myRegExp = '', matchPos, score = objCP.cpEIGetValue('cpQuizInfoPointsscored');
myRegExp = /(please\s.*?(thank you|thanks)|(thank you|thanks)\s.*?please)/i; matchPos = answers[7].search(myRegExp);
if (matchPos != -1) { score += 1; }
myRegExp = /(shows? consideration|be considerate)/i; matchPos = answers[7].search(myRegExp);
if (matchPos != -1) { score += 1; }
myRegExp = /(hold|transfer) (appropriately|as appropriate)/i; matchPos = answers[7].search(myRegExp);
if (matchPos != -1) { score += 1; }
myRegExp = /((use|say) customer'?s? name|call customer by name)/i; matchPos = answers[7].search(myRegExp);
if (matchPos != -1) { score += 1; }
objCP.cpEISetValue('cpQuizInfoPointsscored',score);
objCP.cpEISetValue('rdcmndNextSlide',1);
Then for instance if I enter "Say please and thank you, show consideration, hold as appropriate, say customer's name" my score in the summary slide will show "4" but when I exit the project and look at the attempt the score is still 0.
