For Radio Button

You can use javascript to retrieve the value of the radio button.Save this value in a hidden field in the same form and in the next page just get it by getparameter method.

This is the javascript code to get the value of the radio button which is checked.

function getValue()
{  
 var a=0;
      for(i=0;i<window.document.form1.elements.length;i++)
     {
    if (window.document.form1.elements[i].name=="name")
                if (window.document.form1.elements[i].checked==true)
                    { 
   alert(window.document.form1.elements[i].value + "  is clicked" );
   a=1;
   
  } 
  }
 if(a==0)
 { alert("Please Select A Radio Button"); 
    return false;
 }
 
}

For Checkbox

For checkbos also you can use same method as for radiobutton.

Here i am giving you another function for the same.

function check()
{

   var count=0;
  if(oneCheckedE("number"))
  { 
   for (var i=0;i < document.form1.elements.length;i++)
   {
    var e = document.form1.elements[i];
    
    if (e.type == "checkbox" )
    {

     if(e.checked)
     {
      
      var d = i+1;
      var no=document.form1.elements[d].value;
      
      alert("Number Clicked is "+no);

      
      break;
      
     }
     count++;

    }
   }

  }   
   
}

function oneCheckedE(chkboxname)
  {
   var rowcount=0;
   var numberOfCheckboxs=0;
   for (var i=0;i < document.form1.elements.length;i++)
   {
    
    var e = document.form1.elements[i];
    
    
    if (e.type == "checkbox" && e.name == chkboxname)
    {
     var chkQty=e.name;
     
     if(e.checked)
     {
      
      rowcount++;
     }
     numberOfCheckboxs++;
    }
    
   }
   numberofRows=numberOfCheckboxs;
   if(rowcount<=0 || rowcount > 1)
   {
    alert("Please Select One Checkbox");
    
    return false;
   }else
   {
    return true;
   }
   
   
  
  }
