Body height - Body weight and Male/Female - if I push the Button
the Customer get the size (S/M/L/XL/XXL) i have no idea what must be done
for making the first steps - but i am hanging in the air now how each information together shows a result !!
this ist the script
this is the link http://jsfiddle.net/waycom/71L5vjv5/1/

For some reason, your radioWert function is not defined when you click on the “Your Size” button. It could be an issue with JSFiddle. However, there needs to also be some changes to your existing code:

HTML form:

<input type="button" value="Your Size" onClick="alert(radioWert('myForm', 'radio'))">

Javascript:

 function radioWert(form, rObj) {
     var radioGroup = form.elements[rObj];

     for (var i = 0; i < radioGroup.length; i++) {
         if (radioGroup[i].checked) {
             return radioGroup[i].value;
         }
     }
     
     return false;
 }

Hope that helps
