Hi xtry-

Something like this?

<html>
<title>Calculator Markup</title>

<script language="javascript">
<!--
function reCalc(v) {
var t = document.forms['the_form'].elements['X_Price'];
var prod = document.forms['the_form'].elements['X_Product'];
var p = 2;

if (prod.options[prod.selectedIndex].value != '') {
switch (v) {
case '500':
t.value = (p * parseInt(v)) * .8;
break;
case '8000':
t.value = (p * parseInt(v)) * .7;
break;
case '12000':
t.value = (p * parseInt(v)) * .6;
break;
default:
t.value = '';
break;
}
} else {
t.value = '';
}
}
-->
</script>

<body>
<form name="the_form">
<table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#000000" width="100%" id="AutoNumber1">
<tr>
<td><font face="Verdana" style="font-size: 9pt; font-weight: 700">Product</font></td>
<td><font face="Verdana" style="font-size: 9pt; font-weight: 700">Quantity</font></td>
<td><span style="font-weight: 700">
<font face="Verdana" style="font-size: 9pt">Price per Product \$2.00</font></span></td>
</tr>
<tr>
<td>
<select class="dropdown" style="WIDTH: 99; BACKGROUND-COLOR: #99ccff; height:99" size="1" name="X_Product">
<option value="">Select</option>
<option value="DF6870">DF6870</option>
<option value="EF6890">EF6890</option>
<option value="GF6860">GF6860</option>
</select></td>
<td>
<select class="dropdown" onchange="reCalc(this.value);" style="WIDTH: 99; BACKGROUND-COLOR: #99ccff; height:99" size="1" name="X_Qty">
<option value="">Select</option>
<option value="500">500</option>
<option value="8000">8000</option>
<option value="12000">12000</option>
</select></td>
<td>
<input maxLength="5" name="X_Price" size="20"></td>
</tr>
</table>
</form>

Note:  if the price will always be \$2, and there will always only be those three options for quantity, there really is no calculation needed.  This can be done much simpler, but I assumed you'd wanted the calculation for an actual JavaScript solution.
