Add array to URL string

I know this questions is going to have an easy obvious answer but i have spent over two days now trying to do it with no luck (I am a Flex newbie) Basically i am trying to open a webView that will open google maps to the location in an array

The location comes from data in an array taken from facebook events (that works fine and will display the data) but i am struggling with passing this information to the webView.loadURL string

The data i want in the array is 'data.location' (the code i am having issues with is in the itemrenderer towards the bottom of the code snippet)

I have tried so开发者_JAVA技巧 many different options i am now stuck

all i needed to do was to add the data into the brackets (dont know the offical name) here it is

protected function directions_click (location:String):void
                                {
                                    navigateToURL(new URLRequest('http://maps.google.co.uk/maps?q=' + location));
                                }

and for the button/ label

<s:Label text="Get Directions" fontFamily="lucida grande" fontSize="14" color="#3b5998" click="directions_click(data.location)"/>
