语法错误，意外的T_ELSE[closed]

Question

你能看到为什么我会得到一个意外的T_ELSE错误的原因吗？我一定是瞎了..

<?php
//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 "<script language=\"javascript\">alert('The field was left empty. Please insert your PayPal email address and try again.');</script>";
        }
} 
?>
