Dialog boxes

OK I'm trying to write a menu (dialog) based DJ chair, but I can't seem to get past the "if (llAvatarOnSitTarget() != NULL_KEY)" statment. I've set the llSitTarget in the state_entry() function, but when you sit on the chair... nothing...
anyway here's the whole of the code (except the mutipul if statments), if anyone has any ideas, I'd love to here them.

P.S. Does LSL have something like C's case statment? I'm using a load of if statments but that *must* be so ineffective.

--------------

--------------------------------------------
integer CHANNEL = 42; // dialog channel
list MENU_MAIN = ["1", "2", "3", "4", "5", "6", "7", "8", "9"];


default
{
    state_entry()
    {
        llSetSitText("DJ");
        llListen(CHANNEL, "", NULL_KEY, "");
    llSitTarget(<0.0, 0.0, 0.0>, ZERO_ROTATION);

    }

    changed(integer change) { // something changed
        
        if (change & CHANGED_LINK) { // and it was a link change
            if (llAvatarOnSitTarget() != NULL_KEY) {
            llSay(0,"changed");
            llDialog(llDetectedKey(0), "Choose a station: \n 1 CroniX Aggression (Alternative)  \n 2 1.FX - Channel X (Alternative) \n 3 Radio.Wazee (Alternative) \n 4 Station FM-Les Meillrues (Techno) \n 5 DeviantAudio (Techno) \n 6 PulseRadio (Techno) \n 7 Magic Radio (80's) \n 8 Generation Disco Funk (80's) \n 9 WBITS Internet Radio NL (80's) ", MENU_MAIN, CHANNEL);
        }
           
        }
    }

    listen(integer channel, string name, key id, string message) 
    {
    
    if (message == "1"){
        llSetParcelMusicURL( "http://64.236.34.97:80/stream/1039" );
        llSay(0,message);
    }

       /////// deleted for space
    
    }
}


----------]End of Code[--------------------

I've just realised this also includes my debuging code... please ingore the "llSay(0,"changed";"'s that are littered around.

Well I guess it shows I've tryed to find the problem out myself *grins*

You need to set your sit target to something other than <0,0,0>. Even <0,0,.1> is ok.
Just all zeros clears it.

if (llAvatarOnSitTarget() != NULL_KEY) {
llSay(0,"changed";
llDialog(llAvatarOnSitTarget(), "Choose a station: \n 1 CroniX Aggression (Alternative) \n 2 1.FX - Channel X (Alternative) \n 3 Radio.Wazee (Alternative) \n 4 Station FM-Les Meillrues (Techno) \n 5 DeviantAudio (Techno) \n 6 PulseRadio (Techno) \n 7 Magic Radio (80's) \n 8 Generation Disco Funk (80's) \n 9 WBITS Internet Radio NL (80's) ", MENU_MAIN, CHANNEL);
}

}
}

listen(integer channel, string name, key id, string message)
{

if (message == "1"{
llSetParcelMusicURL( "http://64.236.34.97:80/stream/1039" );
llSay(0,message);
}

}
}




you cant use llDetectedKey(0) in change event use llAvatarOnSitTarget() insted

Thanks
