hmm.. I am not sure if JS is the best sollution for that. I am pretty sure that
there is a way with php for that.
The basic problem comes down to not be able to sort an array customized.
Lets take this array as an example:
$code[language] = array("1"=> "php", "2"=> "asp");
There must for sure be a way to pull the values out of that array by "first in
first out".
I am stuck with this, but it seems logical that there is a way around it.
Thank you for any help on that problem,
Merlin
