SetScriptState

i have made a script that put on or off another script.
The script seems to working but the other script which is put off
is still running after a hour (Checked the script but the check by
running is gone).
Does somebody know what i am doing wrong?

integer chan = 2; //This is the channel the script will listen to.

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

     listen(integer channel, string name, key id, string message)
    {
     
        message = llToLower(message); //convert message to lowercase
        
        if(message == "on")
        {     
            llSay(0, "Teleport On");
            llSetScriptState("Teleport Script",1);                
        }
        if(message == "off")
        {     
            llSay(0, "Teleport off");
            llSetScriptState("Teleport Script",0);                  
        }
    }
}

The teleport script is only use for testing if it works i want to set more script on or off
the script are both in the same single prim.

So, it responds by saying "Teleport On" or "Teleport Off"?

And you are sure that the name of the other script is "Teleport Script"?

(just so we're clear so far . . . )

its responds to '/2 on' or '/2 off' and the name of the script is good.
and the checkbox Running from the script 'Teleport Script' goes on or off but
the teleport script still works when the checkbox running is out (empty).

i thought its maybe the lag but after more than a hour the teleport script is still
working and the checkbox running from the teleport script is still out (empty)

When you say it's still running... are you sure? For example, from the wiki:
...which might give some illusion that a teleport is still active.

yes the Teleport script is still running because i used it to teleport to another room.

Is there another way to make a script active/inactive from another script?

I'm assuming your teleporter uses a sit target? Sit targets are a property of the prim, not the script - although they are configured and enabled by scripts. So even with the script disabled, the sit target would still be active, which would be giving you the teleport effect.

As both Pale and Stephen have already stated the sit target is a property of the prim, once set it is persistant. The script is is in the same prim so send it a linked message to set the sit target to 0,0,0 in the other script before you disable it.

Thanks guys, its working now.
