Retrieving value from radio buttons using struts tag(Please let me know if my quest is not clear)

[Maan Suraj]

  <td class="infoText"> 
     <html:radio property="DebitCard" [b]value[/b]=""  tabindex="-1" styleId="radio"   

       titleKey="StundentOne"> 
     </html:radio>  



      <label for="DebitCard" > 
         <bean:write  name="AbcForm" property="DebitCard"/>
</label> 
   </td> 
                                 
 
   </tr> 
 </logic:notEqual> 

I want to retrieve the value of the radio buttn on selection of the particular radio button.The number of radio buttons dispayed based on some business logic. So there will be different number of radio buttons displayed with some value each time the user enters the value.
Now i want o know how can i retrieve the value of the radio button . I knw that there is an attribue named "value" available with <html:radio> tag.
but value has to be retrieved from some bean property.How can i do that?

I tried in javascript like

var value=document.forms[0].DebitCard[i].value;

but this gives me ""
