[flexcoders] new to flex, tutorial code doesnt work!

[funkbunny08]

Hi, I'm brand new to flex using flex builder 3. I'm trying to build
the simple RIA from the Adobe tutorial and I get a parse error, even
though the code is identical.
Here is the code:
<mx:TileList width="100%" height="100%" />
    dataProvider="{photoFeed}";
    <mx:itemRenderer>
        <mx:Component>
            <mx:VBox width="125" height="125"
                paddingBottom="5"
                paddingLeft="5"
                paddingTop="5"
                paddingRight="5">

                <mx:Image width="75" height="75"
                    source="{data.thumbnail.url}"/>

                <mx:Text text="{data.credit}"/>
            </mx:VBox>
        </mx:Component>
    </mx:itemRenderer>
</mx:TileList>

Any ideas? I dont want to fall at the first hurdle.!
Secondly, can you recommend any decent books or websites that have
good tutorials for the complete beginner. I'm comfortable with css and
html so I'm not a complete noob!

Cheers guys

Paul
