[HELP] NPC Quest

[deregudegu]

Hello,
This is my quest npc's script:
[Java] NPC Quest - Pastebin.com

It don't work.
I would like its changing items 03991005, 03991011 by item 03991000 but I would also be able to add a story that looks like a quest.

Thanks.

status = -1;
req = [03991005, 03991011, 03991000, 03991012, 03991004];

function start() {
    var text = "Hello there! I am the <insert purpose of NPC here> of <insert server name here>! To be able to proceed you need to have 1 piece of the following items:\r\n";
    for (var i = 0; i < req.length; i++)
        text += "\r\n#o"+req[i]+"#"; // I believe #o shows the Item image.
    text += "Do you have those items?";
    cm.sendYesNo(text);
}

function action(mode, type, selection) {
    cm.dispose();
    if (mode == 1) {
        if (status == 0) {
            for (var i = 0; i < req.length; i++) {
                if (!cm.haveItem(req[i], 1) {
                    cm.dispose();
                    return;
                }
            }
            cm.sendNext("Insert text here.");
        } else if (status == 1) {
            cm.sendOk("Blabla, thank you for your items.");
            for (var i = 0; i < req.length; i++) {
                cm.gainItem(req[i], -1);
            }
            cm.gainItem(1002553 , 1);
        }
        cm.dispose();
    }
} 

I really couldn't figure the purpose of your NPC so I made you one which I thought would server it. Do tell me if it needs some modification of any sort.

You know what's good about the .bat when an NPC doesn't work? It shows an error..
