Okay, so here’s the situation. In AS2.0, Flash was a little more lenient with when things didn’t exist. This was valid:

```auto

if (typeof (this.storedPositions[curX][curY]) != 'undefined')
{
   // Return the value
}

```

But in AS3.0, it’s a little more snarky. If the [curX] item does not exist, it throws a hissy fit and makes much sadness. For example:

“TypeError: Error #1010: A term is undefined and has no properties.”

This has resulted in me doing something like so:

```auto

if (this.storedPositions[curX] is Object)
{
   if (this.storedPositions[curX][curY] is Object)
   {
      // Return the value
   }
}

```

I dunno… that just seems a little… inefficient.

Is there a better way of dealing with this situation?
