Radio Button Troubles.

[cbishop01]

Hello I have 3 radio buttons.  When one is selected English, E/F or E/S will Be placed before ©.  Each works fine Until i hit all 3 then it displays all 3 in front of the ©.  For instance if i Click on English(on accident) and then hit E/F  it displays both --- English E/F © when it should just be E/F ©

  var RBT = function(p, label, v, callback) {  
  var rbt = p.add('radiobutton', undefined, label);   
    rbt.onClick = function() {  
    ev.dispatchEvent ( (rbt.value? "ADD_ACTION":"REMOVE_ACTION"), {label:label, callback:callback} );  
  }  
  return rbt;  
  };  

    new RBT ( p6, 'ENGLISH', false, cb20CallBack );
    new RBT ( p6, 'E/F', false, cb21CallBack ); 
    new RBT ( p6, 'E/S', false, cb22CallBack );

function cb20CallBack(target){
      findProps = {findWhat:"~2",}   
        changeProps = { changeTo:"ENGLISH ~2",}   
        grep(target, findProps, changeProps);
      }
function cb21CallBack(target){
      findProps = {findWhat:"~2",}   
        changeProps = { changeTo:"E/F ~2",}   
        grep(target, findProps, changeProps);
      }
function cb22CallBack(target){
      findProps = {findWhat:"~2",}   
        changeProps = { changeTo:"E/S ~2",}   
        grep(target, findProps, changeProps);
      }
