Php $_get question

Hello,

I am trying to echo some information but it is not echoing. The file is called news.php but it is being show through an iframe.

On the first lines I have-

<?php
$info = $_GET["info"];
echo "Info: $info";
?>

On the search bar, I put in ?info=sadfkdsfkjndsf

But nothing is shown on news.php. How can I make it show the variable even if it is an iframe?

Thanks, please help!
