Formatting

Dear list - When I run the following code, the results are preceded by at least one screen full of blank lines. I am showing you a large code block since I do not know where the error is:

    if(isset($_REQUEST['Sex'])&& trim($_POST['Sex']) != '' )
    {
        if ($_REQUEST['Sex'] === "0")
        {
            $sex = 'Male';
        }

        else
        {
            $sex = 'Female';
        }

     }
            $allowed_fields = array
                ('Site' => 's',  'MedRec' => 'i', 'Fname' => 's', 'Lname' => 's','Phone'=> 's',   'Height' => 'i',   'Sex' => 's',
                'Hx' => 's','Bday' => 's',  'Age' => 'i'
                );

            if(empty($allowed_fields))
            {
                 echo "ouch";
            }

            $sql12 = 'SELECT * FROM Intake3 WHERE 1';
