Value selected option dropdownbox
<p>I've got a dynamic dropdownbox:</p>

<pre><code>function chgAantal(i,artNr,lengte){
    var aantal=document.getElementById("aantal_"+i).value;
    if(isNaN(aantal)){
        alert('Voer een geldig aantal in...');
        document.all["error_"+i].src="/images/fout.gif";
        ok=0;
    }
    else{
        location.href="addcart.asp?act=change&amp;aantal="+aantal+"&amp;artNr="+artNr+"&amp;lengte="+lengte+"&amp;bdr=&lt;%=bdr%&gt;";
    }
}
&lt;select onchange='chgAantal(\""+i+"\",\""+artNr+"\",\""+lengte+"\")' name='aantal_"+i+"' value='"+aantal+"'/&gt;
&lt;option value='1'&gt;1&lt;/option&gt;
&lt;option value='2'&gt;2&lt;/option&gt;
&lt;option value='3'&gt;3&lt;/option&gt;
&lt;option value='4'&gt;4&lt;/option&gt;
&lt;option value='5'&gt;5&lt;/option&gt;
&lt;option value='6'&gt;6&lt;/option&gt;
&lt;option value='7'&gt;7&lt;/option&gt;
&lt;option value='8'&gt;8&lt;/option&gt;
&lt;option value='9'&gt;9&lt;/option&gt;
&lt;/select&gt;
</code></pre>

<p>When I change the value in (for example) 7, the value changes in the script. But I can't see the selected value, the value displaying is always 1. 
How can I display the selected value?</p>

<p>I hope you understand me!</p>

<p>Regards,</p>
