I have some radio buttons in a table and I’ve set a value to them. When the user selects them and clicks the submit button, I want the sum of those values to show in another tab
You can create a function that you'll call on click in that you can use
if (document.getElementById('a1_1_0').checked) { value = document.getElementById('a1_1_0').value; }
And so on for all the Radiobuttons
