I’ve downloaded Flex 3 and got it working, and I’m trying to create a vector array of integers using the line of code below, but when i compile I get an error highlighting “Vector” and saying it’s not a compile time constant. I’m a total newb to Flex (i only got it working thanks to senoculars tutorial), so I’m wondering if there’s some extra thing i have to download to use Flash Player 10 stuff like vectors? Or is there something else I’m doing wrong? I downloaded Flex 3 from adobe’s website fairly recently…

```auto
var thing:Vector.<int>=new Vector.<int>;

```

EDIT: Btw, i’m using the Flex SDK, NOT Flex Builder
