    An idea could be to take onsubmit() out of the form tag.

    then for your button change the onSubmit to onclick='return verifyForm();

    In your verifyForm() method you need to return either true or false; if false, the form won’t submit.

    So, something like this at the end of your verifyForm() 

    if (FinalMsg == ""){
    return true;
  }else{
   return false;
 }
