I having to issues with my code. the first one is that I am trying to format The Total as currency but it does not work. my second issues is I am using the Reduce() method to track and calculate the price when ever the user selects the item till here it works find, but when the user unselects an item it goes back to zero . I do not that I just want to mince it and keep the selected once .

const items = useSelector((state) => state.cartReducers.selectedItems.items);
 
const Total = items
  .map((item) => Number(item.price.replace("$", "")))
  .reduce((prev, curr) => prev + curr, 0);
    
const USD = Total.toLocaleString("en", {
  style: "currency",
  currency: "USD",
});
