llMoveToTarget() not working in HUD or attachment

Greetings,

I have the following bit of code in a hud although I've also tried it in an attachment. Everything works fine with the exception of the llMoveToTarget call. My av doesn't move at all. If I move the my AV manually to the target the at_target event fires correctly (I'm going to replace at_target with collision).

state kiss
{
    state_entry() {
        avFindName = TRUE;
        llSensor( "", NULL_KEY, AGENT, sensorDistance, PI );
    }
    
    on_rez( integer startcode ) {
        llResetScript();
    }
    
    sensor(integer total_number) {
        if ( avFindName ) {
            integer i;
            for ( i = 0; i < total_number; i++ ) {
                if (llDetectedName(i) == avTarget && llDetectedKey(i) != llGetOwner() ) {
                    avName = llDetectedName(i);
                    llWhisper(0, "You have offered to kiss " + avName + "." );
                    llMessageLinked( LINK_THIS, linkChannel, linkStringRequest, llDetectedKey(i) );
                    avName = llList2String( llParseString2List( avName, [" "], [] ), 0 );
                    avKey = llDetectedKey(i);
                    return;
                }
            }
        }
        else {
            avPos = llDetectedPos(0);

	    targetID = llTarget(avPos, 0.5);
	    llMoveToTarget(avPos, 0.2);            
        }
    }
	
    at_target(integer tnum, vector targetpos, vector ourpos)
    {
	llTargetRemove(targetID);
	llStopMoveToTarget();
...

Any ideas as to why the llMoveToTarget is failing?

There is a bug that makes llMoveToTarget() fail when you edit a script. Try detaching the object and re-attaching again without editing the script.
