the first time you load the page, $_GET[] is empty, not populated until the form is submitted,, code not checked count {braces}

if(isset($_GET['submit'])){if($_GET["uname"]){echo "your name  is".$_GET['uname'];}}
  else {echo"please enter your name";}

I agree with @almostbob but also your <form> is empty where you should pass an action and a method for example <form action='nameofpagehere.php' method='get'>
