Not Getting Permission for Animation

The following script plays a priority 4 animation for the arm holding the object in which it is loaded and puts a stupid perma-grin on the avatar's face. To my complete and utter consternation, however, the 'Hold' animation continues to override other lower priority animations after the object is has been detached. Unsurprisingly the object throws a script error warning "Script trying to stop animations but PERMISSION_TRIGGER_ANIMATION permission not set" when it is rezzed in-world:

default
{
     attach(key avatar)
     {
     llRequestPermissions(llGetOwner(),PERMISSION_TRIGGER_ANIMATION);
    }
        
    run_time_permissions(integer value) 
    {
            if (value & PERMISSION_TRIGGER_ANIMATION) 
            {
             llStartAnimation("express_toothsmile");
             llSetTimerEvent(1);
            }
     }
 
     timer()
    {
        llStopAnimation("express_toothsmile");
        llStartAnimation("express_toothsmile");
        llStartAnimation("Hold");
    }          
}

Perhaps I should be wearing the stupid perma-grin myself?

The timer will still be running after first attach. try adding an on rez event:

on_rez(integer start_param) {
if (llGetAttached() == 0) {
llSetTimerEvent(0.0);
}
}

Thank you, Escort. This appears to have done the trick. I'm reproducing it here for inspection. Even though I'm quite experienced at torturing other people's scripts into doing my bidding I don't fully understand the syntax of scripting:

default
{
on_rez(integer start_param)
{
    if (llGetAttached() == 0)
    {
        llSetTimerEvent(0.0);
        }
        }
        attach(key avatar)
        {
            llRequestPermissions(llGetOwner(),PERMISSION_TRIGGER_ANIMATION);
            }
            run_time_permissions(integer value)
            {
                if (value & PERMISSION_TRIGGER_ANIMATION)
                {
                    llStartAnimation("express_toothsmile");
                    llSetTimerEvent(1);
                    }
                    }
                    timer()
                    {
                        llStopAnimation("express_toothsmile");
                        llStartAnimation("express_toothsmile");
                        llStartAnimation("Hold");
                        }
                        }

what about having it turn off the timer when it detaches, that way if it's rezzed on the ground it never needs to perform the check

default
{

attach(key avatar)
{
if(avatar)//if there's an actual key and not NULL_KEY
{
llRequestPermissions(llGetOwner(),PERMISSION_TRIGGER_ANIMATION);
}
else{llSetTimerEvent(0.0);}
}
run_time_permissions(integer value)
{
if (value & PERMISSION_TRIGGER_ANIMATION)
{
llStartAnimation("express_toothsmile";
llSetTimerEvent(1);
}
}
timer()
{
llStopAnimation("express_toothsmile";
llStartAnimation("express_toothsmile";
llStartAnimation("Hold";
}
}

Although that seems a cleaner approach, it is more fragile. The reason for that is that attach isn't guaranteed to run when you detach an object and so the timer may not be stopped.

Huh. Don't think I've ever seen it NOT run. Where's that info from? I know the amount of time your attach handler can take during detach is somewhat limited, so you don't want to run stuff that causes script delay and such, but I wasn't aware of it not running at all.
