Here is my scriptlet:

new Effect.Parallel
([
new Effect.Tween($("TickTach"), 1200, 120, "height", {sync: true}), 
new Effect.Tween($("TickTach"), 1600, 160, "width", {sync: true})],
{duration: 1}
);

It throws an object is null error in the Tween function in scriptaculous

Effect.Tween = Class.create(Effect.Base, {
 initialize: function(object, from, to) {
 object = Object.isString(object) ? $(object) : object;    
 var args = $A(arguments), method = args.last(),
 options = args.length == 5 ? args[3] : null;
 this.method = Object.isFunction(method) ? method.bind(object) :
 Object.isFunction(object[method]) ? object[method].bind(object) :
 function(value) { object[method] = value };
 this.start(Object.extend({ from: from, to: to }, options || { }));  },
 update: function(position) {
 this.method(position);
 }
});

I did run across a "try it yourself" in a tutorial, it did not work either...Anybody aware of a problem?

OK, my bad I had defined the div element as "TickTack", but I am still having problems. I will just cross my fingers that someone can help...

I have a <div> with an <img> the image is large (1600,1200) I want to use scriptaculous to tween it down to 160,120 I can set width and height of <div> to 160 x 120 and <img> to 100%,100% and all is well, but tween will not work...

Please help if you can
