I guess the problem is if all the radio was not cheked then it will keep popping up.. maybe try to check the radio button if either is check not all...

What's the code that calls the validate function?  And what's the code after your 'return false' statement?

function validate(formname)

{

 

for (var i = 1; i <= formname.numQtns.value; i++)

          {

      radioGroup = document.getElementById('Q' + i);

            }

if(!radioGroup.checked)

              {     

            alert('Please answer all questions before submitting.'+i);

            return false;

                  }

  }

 

 

place the false condition after the for loop.it will work.
