php - syntax error, unexpected T_ELSE

Can you see any reason why I would be getting an unexpected T_ELSE error? I must be blind..

//Check if form was submitted
if(isset($_POST['submit']))
{   
    //Form was submitted.

    if($_POST['paypalemail'] != '');
    {
        //An email was submitted.
    } 
    else
        {
            //There was nothing in the field. Tell them.
            echo "";
        }
} 

?>
