First, in order for you to earn credits, you first have to be flagged by the quest NPC for earning credits. The actual kills themselves don't flag you for that, because I didn't want it to do more work for every kill and I also didn't want to risk any possible reset of credits.

So, you need to use one of the other quests I posted here first.

Also, for this to work on a global level, you have to edit the option in the globals to 5 instead of 1. So, note the following and see where I marked it in RED:

quest::setglobal("exp_credits", $qglobals{exp_credits}+1, 1, "F");

If you want this global to be seen by all NPCs in all Zones, you need to change every flag to use option 5 like this:

quest::setglobal("exp_credits", $qglobals{exp_credits}+1, 5, "F");

That should resolve both of your issues. Lemme know if you have any more questions.
