Design issue with Flex

Question

I am working with Flex 3.0. I am trying to nest VBoxes within a TabNavigator and that works fine. But in my first VBox I have two buttons which won't show. I am not great with design concepts anyway and am new to Flex. I have tried messing with width and height properties, using an Hbox. Could someone take a look and figure out what I could do to fix these. Here is the full Panel. The TabNavigator is close to the bottom.

<mx:Panel id="pnlMain" label="Address Search" width="100%" borderStyle="none" headerHeight="0">
    <mx:ViewStack id="vsAddressSearch" resizeToContent="true">
        <mx:Form id="frmAddressSearch" styleName="measureForm" width="300" height="100%" fontFamily="Arial" fontSize="11" verticalGap="0" horizontalGap="0" verticalScrollPolicy="off" horizontalScrollPolicy="off">
            <mx:FormItem label="Address:" paddingBottom="5" paddingTop="5" textAlign="left" fontWeight="bold" width="100%">                
                <mx:TextInput width="100%" id="txtAddress" text=""/>            
            </mx:FormItem>  
            <mx:HRule height="5" width="100%"/> 
            <mx:HBox horizontalAlign="left" paddingTop="5">
                <mx:Button label="Find Address" click="BingFindAddress()"/>     
                <mx:Button label="Clear" click="clearGraphics()"/>

Answer 1

Your buttons are set to visible="false" so they are not going to show up.

<mx:Button  id="googleButton" visible="false" label="Google Directions" click="newWin('https://maps.google.com/?q=' + addressResult)"/>
<mx:Button id="mapquestButton" visible="false" label="MapQuest Directions" click="newWin('https://mapquest.com/?q=' + addressResult)"/>
