How Do I Tweak This Sensor Script Please

Here is an example of a sensor script I found that returns the sensed avatars names as a Dialog menu. What I'm wanting to do is say a message in open chat or another channel containing the name of the selected avatar. eg if the sensor returnes the names Jack and Jill in the Dialog menu and i press Jack, a message is said using that name. ie Goodmorning (Jack) in open chat or on another channel. Does anyone know how to do this please???

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));
}

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);
}
}

Add a line to the listen event so it reads like this:

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

I suspect, rather, "... + name...".

One might also get fancy and extract the first name, using llSubStringIndex(name, " " to find the space character, and llGetSubString() from 0 to that index.

No, you want message.

In the listen event, name refers to the name of the person the script is listening to... which is the person to used the Dialog. message is the text from the button on the llDialog, which is the names of the people in the area.

Oh, quite right. I actually looked for an llDialog() or anything else that might make that listen() event be something other than somebody talking, but didn't see it in our forum's current "blank verse" formatting. Sorry for the bum steer.

thanks guys, anyone ever tell you that you rock??? Well ya do and if anyone has anything different to say, send them my way

I'm fairly new to scripting and doing what a lot of folks do to learn I think by tweaking existing scripts.

I've found to repurpose this script to have it say the Agent Key instead of the name.
Can this be done?

Thanks for the help, Oh Gurus of LSL.

Thanks folks, I answered my own question...
I adjusted this portion of the script:

listen(integer channel, string name, key id, string message)
{
integer listPos = llListFindList(avatarsDetected, (list)message);
useKey(llList2Key(keysDetected, listPos));
llSay(0,"The uuid for "+message+" is:";
llSay(0, (string)llList2Key(keysDetected,listPos));
}
