How do I display the value on screen for a selection in a radio group array?

Question

I can't figure out how to display the value of a field from a selected radio group.
I've figured out how to pass the value from a dropdown and tried to use similar settings for a radio group to no avail...

I've set the javascript as follows -

function myFunction() {
   
 var x = document.getElementById("checkboxes61").value;
    document.getElementById("demo").innerHTML =  x;

 var y = document.getElementById("discount").value;
    document.getElementById("demo2").innerHTML = y;

var z = Number(x) + Number(y);
    document.getElementById("demo3").innerHTML = z;

var a = z * (.3*10) / 10;
    document.getElementById("demo4").innerHTML = a;

 var b = document.getElementById("radio123").value;
    document.getElementById("demo5").innerHTML = b;

}

Html as follows -

 <body onload="myFunction()"> 


<div style="background-color:lightblue">
<h4>Checkboxes Value</h4>
<p id="demo"></p>
</div> 
<p></p>

<div style="background-color:lightblue">
<h4>Dropdown Value</h4>
<p id="demo2"></p>
</div> 
<p></p>

<div style="background-color:lightblue">
<h4>Add Checkbox and Dropdown fields</h4>
<p id="demo3"></p>
</div> 
<p></p>

<div style="background-color:lightblue">
<h4>Add Checkbox and Dropdown fields then Multiply by .3</h4>
<p id="demo4"></p>
</div> 
<p></p>

<div style="background-color:gray">
<h4>Value of Radio Group</h4>
<p id="demo5"></p>
</div> 
<p></p>

</body>

If I set the id as "radio1230" or "radio1231" it returns the values but when I click on them to change nothing happens...

Same result with the checkboxes as well
