Why Does This Sensor Script Only Work 4 Me

Below is a script that, when placed in an object and the object touched, returns a list of avatar names as a dialog menu. Then when a name is selected, broadcasts it on channel 0 with a preceeding message. Can anyone tell me why, when I pass the object to another person it doesn't broadcast the message when they select an avatar name from the dialog menu???

Thanks

integer channel = -10;
string menuText = "Select your target:";
list avatarsDetected = [ ];
list keysDetected = [ ];

useKey(key targetKey)
{
// This is where you "do something" with that key. I dunno whatYOU plan to do with it
// in my demo in world, I passed it to a particle beam. There's some issues with that
// since the particle target range seems to be the client's draw distance.
// but if you wanted to rez a follower, or whatever, you'd do that here.
}

default
{
state_entry()
{
llListen(channel, "", llGetOwner(), "";
}

listen(integer channel, string name, key id, string message)
{
integer listPos = llListFindList(avatarsDetected, (list)message);
useKey(llList2Key(keysDetected, listPos));
llSay(0, "i love u " + message);
}

touch_start(integer duration)
{
llSensor("", NULL_KEY, AGENT, 100, PI);
}

sensor(integer numDetected)
{
if (numDetected > 12) numDetected = 12;
integer nextStep;
string nextAvatarName;
string nextAvatarKey;
avatarsDetected = [ ];
keysDetected = [ ];
for (nextStep = 0; nextStep < numDetected; nextStep++)
{
nextAvatarName = llDetectedName(nextStep);
nextAvatarKey = llDetectedKey(nextStep);
if (llStringLength(nextAvatarName) > 24) nextAvatarName = llGetSubString(nextAvatarName, 0, 23);
avatarsDetected = (avatarsDetected=[]) + avatarsDetected + nextAvatarName;
keysDetected = (keysDetected=[]) + keysDetected + nextAvatarKey;
}
llDialog(llGetOwner(), menuText, avatarsDetected, channel);
}
}

Where is the script?

When they rez the object it they click on it and get the dialog box. It just doesn't respond with a message and instead lags them???

When you saved this script, the script got your key as the owner and there was never chance to get anyone else's.
This script is needed to reset after changing owner.

Can you please adivese how to fix this?? Do I add an on_rez event and reset the script there??

Yes, exactly, you're right.

on_rez(integer reset)
{
    llResetScript();
}

Or

changed(integer change)
{
    if(change & CHANGED_OWNER)
    {
        llResetScript();
    }
}

You can put down llListen(channel, "", llGetOwner(), ""; insted of llResetScript();

Thanks Mate Worked Like A Charm !!!
