в хтмле добавь class такой же как и name

<input type="radio" class="training" name="training" value="yes" />да<br />
<input type="radio" class="training"  name="training" value="no" />нет</div>
<input type="radio" class="arrive" name="arrive" value="10" />
<input type="radio" class="arrive" name="arrive" value="11" />
<input type="radio"  class="get_off" name="get_off" value="11" />
<input type="radio"  class="get_off" name="get_off" value="12" />

в функции в низ добавь это

var Arr=new Array()
			Arr[0]='training'
			Arr[1]='arrive'
			Arr[2]='get_off'
			var total=Arr.length
                                  var count=0
			for(var j=0; j<Arr.length; j++){
			var a=document.getElementsByClassName(Arr[j])
			for(var i=0; i<a.length; i++){
			if(a[i].checked==true){count++}
			}
			}
if(count!=total){retVal=false} else {retVal=true}
