using expression manager codes in javascript was created by Moonlight7

Hi everyone,
I have three equation type questions (aScore, bScore, cScore) and I'm trying to use javascript in a Text Display question to sort the results of the three equations in a descending order (since I couldn't find any sorting function available in EM ). I did this :

Code:

<script type="text/javascript" charset="utf-8">
   var points=["{aScore}","{bScore}","{cScore}"]; 
   points.sort(function(a,b){
   return b - a
   })
   document.write(points);
</script>

The above code works well and sorts correctly if I put an array of numbers but what I get when I use the questions codes like shown above is a reverse order of how I put the variables in the array above irrespective of their values.

e.g. assume {aScore} was 3, {bScore} 17, and {cScore} was 5 then the above script would give me : 5, 17, 3 as if the code does not recognise the variables as numbers !

Any views on what I'm missing here please ??

edit: I guess the the problem is that EM {..} are being interpreted after the javascript function ended and I hope this can be solved some way or there is a simpler solution to what I need to achieve.
Thanks so much

Probably working if not "All in one" display. Try group by group or question by question presentation

Try removing the quotes from the array elements so they're not interpreted as strings.

Code:

var points=[{aScore}, {bScore}, {cScore}];

@Ben, thanks that solved it when put on a later page. I wish I could make it work on same page though.

Thanks Tony but putting the quotes was the only way to make EM work! If I remove them the {} get stripped and no more useful !
I am just learning by trial and error !
