Problem with sending form data by Query string

[eluser]Unknown[/eluser]
Hi,

I have form which is having one text field, named by CompanyName. when I submit the form it submitting as query string (form method is GET )as i want. The following is sample URL for that : http://localhost/index.php/Companysearch...me=Darwish

I'm trying to get CompanyName within my result function as follows:

Code:

function result(){
  if(isset($_GET['CompanyName'])){
    $comName = $_GET['CompanyName'];
  }
  echo $comName;
}

My problem is that, it says $comName is undefined variable. Is there any wrong in my code?.
or can't we use like above?

Please guide me how to sort out this
