Topic awaiting preservation: Please help - Javascript loop!

Hi!

Could you please help me with Javascript.

I've got 3 <select> fields with names month1, month2, month3.
so it's

<select name="month1">
<option value=1>1
<option value=2>2
<option value=3>3
</select>

<select name="month2">
<option value=1>1
<option value=2>2
<option value=3>3
</select>

<select name="month3">
<option value=1>1
<option value=2>2
<option value=3>3
</select>

I need to run a loop to count the total of months selected for these 3 fields.
So if the customer selects 1 (for month1), 2(for month2), 3 (for month3) then the total=1+2+3=6.

Javascript:

<script language="javascript">
<!--

var i = 0;
var sumtotal=0;

for (i = 0; i < 4; i++)
{sumtotal= document.wizform.monthvalue[i].options.value;}
alert (sumtotal);

// -->
</script>

Not working! document.wizform.monthvalue[i].options.value - Javascript can't understand what the value is. I NEED to use the loop here (i've got plenty of <select> fields... here is only 3 - just for example.... please help. Thanks Helen.

<script language="javascript">



var sumtotal=0;

for(j=1;j<3;j++){

 var box = document.getElementById("month"+j)

 var i = 0;

 while((opt = box.options.item(i++))){

  if(opt.selected){

   sumtotal += parseInt(opt.value);

  }

 }

}

alert (sumtotal);

</script>

One way of doing it...

Sorry I can't see the reply post.

hold on. I can now...

Oh btw, that's if the user can select more than one option from every selectbox.
In case I misunderstood you the first time, here's a much shorter version if you
allow the user to select only one option from each list.

<script language="javascript">

var sumtotal=0;

for(j=1;j<3;j++){

 var box = document.getElementById("month"+j)

 sumtotal += parseInt(box.options[box.selectedIndex].value);

}

alert (sumtotal);

Sorry about that
