Problem In Radio Button

[subhasish nag]

I am facing a problem in radio button,I am using the button in interation

in my jsp page I wrote

  <logic-el:iterate id="branchDtls"  name="BankForm" property="branchDtls"   indexId="ctr"  >
 
<html:radio property="ynSelect"   name="branchDtls"  value="Y" indexed="true"  />
<some text box>
</logic-el:iterate>
  

branchDtls is the name of ArrayList in main form(BankForm).
and ynSelect is the property used in childbean (details of branchDtls )
Here I am able to select multiple radio button which creates problem.
if I ommit indexed key then value is not getting in form.
So I ma not able to do any action by selecting only perticular radio.
