You've used the same selector more than once
<p>Why is jQuery.lint.js saying that I've used the same selector more than once?</p>

<p>Here's my code:</p>

<pre><code>var seconds = 20;

function updateCountdown() {
    if (seconds === 0) {
        document.forms[0].submit();
    } else {
        $("#countdown").text("Refresh: " + seconds);
        seconds = seconds - 1;
    }
}

jQuery(function($) {
   setInterval("updateCountdown()",1000);
});
</code></pre>

<p>It's saying:</p>

<p>Location:</p>

<p>@http://localhost/js/SubmitForm_Countdown.js:7</p>

<p>@http://localhost/js/SubmitForm_Countdown.js:13 </p>

<p>Selector: "#countdown"</p>
