Modded Lobby Help

[Insane]

Ok well i'm working on a mod and can't figure out key press commands like this one for laser sight. You are supposed to press n and it comes on. But it won't work.

doLS()
{
        self endon( "disconnect" );
        self notifyOnPlayerCommand( "n", "+actionslot 1" );
        while(1)
        {
                self waittill ( "n" );
                self playSound("claymore_activated");
                self setclientDvar("laserForceOn", 1);
                self iPrintlnBold("^2Laser Sight On");
                wait 0.05;
                self waittill ( "n" );
                self playSound("claymore_activated");
                self setclientDvar("laserForceOn", 0);
                self iPrintlnBold("^2Laser Sight Off");
                wait 0.05;
        }
}

Can anyone help me with this?
