has idea i'm going wrong? appreciated.

thanks.

if use console.log on response object, you'll realize includes "error" property , response.error.message "an access token required request resource."

you can check if response includes error using following:

function (response) {     if (response.hasownproperty("error")) {         alert("error: " + response.error.message);     } else {         //success!     } }

for error, similiar question can found here: "an access token required request resource" while accessing album / photo facebook php sdk
