Problem: Default checked radio button value shows on app, but if I change the tip value, then unselect and reselect a checkbox, it goes back to the original checked radio button value instead of changing to the new tip value.

Basicaly, my default radio checked button value is set to $5. If I select a checkbox option, then I change the tip value to $2 then unselect a checkbox, then reselect a checkbox, it will show the tip value as $5 instead of the new option $2

Here's my codepen. I added instructions on the codepen so you can see my problem

Here's my JS

window.menuItems = 0;
window.tips = 0;

const foodTotal = document.getElementById("price");
const tipTotal = document.getElementById("tip");
const orderTotal = document.getElementById("total");

let tipVal = document.querySelector(".tips:checked").value;

tipTotal.textContent = "$" + (tipVal / 100).toFixed(2);

document.addEventListener("click", ({ target }) => {
  if (target.className === "food" && target.checked && tipVal) {
    window.menuItems += parseInt(target.value);
    window.tips = tipVal;
  } else if (target.className === "food" && !target.checked) {
    window.menuItems -= parseInt(target.value);
  } else if (target.className === "tips" && target.checked) {
    window.tips = parseInt(target.value);
  } else {
    return;
  }

  foodTotal.textContent = `$${(window.menuItems / 100).toFixed(2)}`;
  tipTotal.textContent = `$${(window.tips / 100).toFixed(2)}`;
  orderTotal.textContent = `$${(
    (Number(window.menuItems) + Number(window.tips)) /
    100
  ).toFixed(2)}`;
});

I can't seem to convert the logic to make the tip value to change after I unselect & re select a checkbox option.
