You can't return a response from an asynchronous callback function. But you can store the return value in a global variable or display it in a <div> on your page. You need to do whatever you need to do with it inside the callback function (where you have your alert). What do you want to do with the returned value? -- Larry -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
