you can check it out at http://indiantweets.in

url : "gettwitt.php?val=0&media=med-16",
///                                   ^ Add a " there, like I have done.

You have failed to close the string with a matching delimiter. Add a closing " to your first string.

Also false and "false" are two different things, with the latter being equivalent to true (as it is a non empty String) and not false. Drop the quotes there.
