Try this...

$query = "SELECT * FROM admin WHERE userid = '$id'";
$result = mysql_query($query);
if (!$result){
  die('Could run query: ' .mysql_error());
if(mysql_fetch_row($result)){ // We're only expecting one row, so mysql_fetch_row should be fine
  echo '<a href="form.php">Go back</a> username is taken!
