Answer 1

You are not assigning any value to the radio button. Add this to your code and check :-

<script type="text/javascript">
    function EveryDay() {
    document.getElementById('RdIsPerDay').checked = true;
    document.getElementById('RdIsPerWeekDay').checked = false;
    //add this to your code
    document.getElementById('RdIsPerDay').value= true;
    document.getElementById('RdIsPerWeekDay').value= false;

    document.getElementById("txtPerDay").style.visibility = 'visible';
    document.getElementById("lblPerday").style.visibility = 'visible';
}
function EveryWeekDay() {
    document.getElementById('RdIsPerDay').checked = false;
    document.getElementById('RdIsPerWeekDay').checked = true;
    //add this to your code
    document.getElementById('RdIsPerDay').value= false;
    document.getElementById('RdIsPerWeekDay').value= true;

    document.getElementById("txtPerDay").style.visibility = 'hidden';
    document.getElementById("lblPerday").style.visibility = 'hidden';
}
</script>
