Concatenation, Javascript, and general bafflement :)

Hi!

I'm new to storyline and have been furiously googling to put together a quiz. At this point, it's a bit of a monster, with ~ 30 user defined variables that need to be sent back to the LMS. There are ways to send individual variables to a short answer slide, which then could be reported to the LMS server, but I would rather not make 30 short answer slides. 

My current plan is to concatenate my variables into a single text string in javascript, with that single text string reported to a LMS. I'm basing this setup on several user discussions, including the following:

(if I missed your discussion, please let me know )

I've attached a copy of two question sets in the attached file. I decided to make my question slides, with variables indicating the first answer choice (A03Local, A06Map) and the number of tries (A03Interact, A06Interact). Ideally, I want this to be concatenated in a single variable (final) which is then fired off to the LMS under the radar. I'm kinda baffled at this point :) 

Thanks!

Hi -

When I first started using storyline, it made sense to make my own question slides with user defined variables - and storyline was powerful enough to let me initially get away with it   I didn't want a visible focus on quiz elements (submit, correct, incorrect) on the user side, but I did want to track the initial answer and the number of tries to get the correct answer. Unfortunately, I'm just past the halfway point of my 30 day trial - I'm not sure if I have time to rewrite all the slides...

As you said, I'm trying to send all my user defined variables in a single interaction. I've had some trouble running past examples of storyline with javascript (ie did_it.story @ http://community.articulate.com/forums/p/12464/74682.aspx) on my computer, so I'm wondering if it's a broader problem or my programming specifically. I also haven't plugged this into a SCORM yet - I'll be using blackboard, but may test drive it in articulate online.

The javascript that I'm using reads as follows:

var player = GetPlayer();

var a= player.GetVar("A03Interact");

var b= player.GetVar("A03Local");

var c = player.GetVar("A06Interact");

var d = player.GetVar("A06Map");

var e = "Question A03 answer: " + b + "~Question A03 tries: " + a + "~Question A06 answer: " + d + "~Question A06 tries: " + c;

player.SetVar("final",e);

Thanks! JJ
