Hi Everyone,

quick question about the this.watch(“variable”, function, args)  
tag, does anyone know how to get this to watch a variable within an array or object, for example : i have an array

```auto
myArray = new Array('jello', 'pizza', 'pie', 'coke')

```

then I have a MC with the code:

```auto
_root.watch("myArray[1]", traceMe)
//
function traceMe(a,b,c)
{
    trace(c)
    trace(_root.myArray[1])
}

```

So, whenever I change the data in Array[1] I want the MC to trace the result…can this be done?

Also, does anyone know any reason why I shouldn’t use the Watch tag?  
I haven’t seen it used much before, but I really like it, so I was kinda wondering if there was any reason why it is rarely used…

thanks in Advance C:-)
