Multiple dialogs?

Okay, hopefully someone can help me out here as I'm fairly new to scripting with LSL. I'm currently working on creating a HUD object for myself to use, and I want it to have a menu-driven system.

As it stands, I currently have the very basic part set up. It shows an initial dialog upon touching the object the script contains, like so:

    state_entry()
    {
        llDialog(llDetectedKey(0),
                "Please choose an option below.",
                ["Button 1", "Button 2"],
                channel);

        listenid = llListen(channel, "", llDetectedKey(0), "");
    }
    
    listen(integer chan, string name, key id, string mes)
    {
        llListenRemove(listenid);
    }

I tried having "mes" in a switch statement which called another "llDialog" depending upon which button was pressed, but it seems that the second call to "llDialog" is just ignored.

How can I properly set this up to bring another dialog up after the first selection has been made? Any help would be GREATLY appreciated. Thanks! ^_^

Nevermind...

Seems I was being stupid and tried using llDetectedKey(0) in the second request, and it wasn't getting passed properly for whatever reason. Just replaced it with llGetOwner() and it's working fine.

I guess llDetectedKey(0) only works inside of handlers like state_entry, etc? Man, LSL confuses me sometimes...

...check out the key id in the listen event though.

That's the agent the listen had detected.
