I use the "simple calculation" with radio buttons with this code:
<script type="text/javascript"> 
function calculate() 
{ 
    var op1=document.getElementsByName('form[radio1]'); 
    var op2=document.getElementsByName('form[radio2]'); 
    var result=document.getElementById('result'); 
    result.value=0; 
    result.value=parseInt(result.value); 
    for(i=0;i<op1.length;i++) 
        if(op1[i].checked) result.value=parseInt(result.value)+parseInt(op1[i].value); 
    for(i=0;i<op2.length;i++) 
        if(op2[i].checked) result.value=parseInt(result.value)+parseInt(op2[i].value); 
 
    return false; 
} 
</script>

Now i want a quantity supplement between radio1 and radio2, maybe with a numeric textbox, so that the multiplication takes only efekt to the radio1 value. {(radio1 * quantity)+ radio2}

Can someone help me how i must change the code?

Thx.

Hello,

You could try setting the quantity field to be required and modifying this line of your script:
if(op1[i].checked) result.value=parseInt(result.value)+parseInt(op1[i].value); 
 
if(op1[i].checked) result.value=parseInt(result.value)+(parseInt(op1[i].value)*parseInt(quantity_field).value);
Also you should trigger this script when filling in the quantity field as well by adding this line in the "Additional attributes" property of your quantity field:
onkeyup="calculate();"
