When i run this, i get the select list alright, but it does not seem list the list is passing comparing indexes with jira

Can you expand on this? Since the only thing your code does is create a select list, and you say it is "alright", what is it that you want to be different? Does jira expect different values than the 0,3,5?

$m->out(</select>);

That should be $m->out('</select>'). Maybe that's your problem?
