javascript countdown
<pre><code>&lt;span id="count_down"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;script type="text/javascript"&gt;
var bum=0
var seconds=7
function display() { 
 if (bum&lt;=0){
    bum=9 
    seconds-=1
}
if (seconds&lt;=-1){
    seconds+=1
} else
    bum-=1 
    document.getElementById('count_down').innerHTML=seconds
    setTimeout("display()",100) 
}
display()
&lt;/script&gt;
</code></pre>

<p>It's count down from 7 to 0. I wanna this script to count down from 7 to 1 and instead of 0 showing display text like: omg, zero reached! or smth. And if can please make this script more "beautifier" or more simple, because in my mind var bum doesn't needed.</p>
