Value selected option dropdownbox

I've got a dynamic dropdownbox:

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&aantal="+aantal+"&artNr="+artNr+"&lengte="+lengte+"&bdr=<%=bdr%>";
    }
}
<select onchange='chgAantal(\""+i+"\",\""+artNr+"\",\""+lengte+"\")' name='aantal_"+i+"' value='"+aantal+"'/>
<option value='1'>1</option>
<option value='2'>2</option>
<option value='3'>3</option>
<option value='4'>4</option>
<option value='5'>5</option>
<option value='6'>6</option>
<option value='7'>7</option>
<option value='8'>8</option>
<option value='9'>9</option>
</select>

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?

I hope you understand me!

Regards,

Fraak

You should not be specifying the value in the Select tag as is determined by the selected option. Useful DOM properties for working with select Elements are:

selectedIndex: gets/sets the Id of the selected option.
value: returns the value of the selected option.

What you need to do here is change selectedIndex.
