Why my JavaScript Shopping cart is not working correctly?

Hi! So I decided to challenge myself and create a webpage that has a table and a shopping cart using JavaScript, but after a month of playing around with my code, I can't seem to debug it anymore. I have placed my JavaScript code below for my array.js and cart.js files that I am using and any help on this matter is greatly appreciated!

arrays.js code

"use strict";  
var item = ["Hummus", "Lamb", "Cake"];
var price = ["$3.00", "$11.00", "$12.00"];
var qty = ["1", "1", "1"];
item[0] = "Hummus";
price[0] = "Lamb";
qty[0] = "1"

cart.js code

"use strict";  
var subtotal = 0;
var cartHTML= '<table><thead>'+ 
'<tr><th>Item Description</th><th>Price</th><th>Qty</th><th>Total</th></tr>'+ '</thead><tbody>'; 
for(var i=0; i< item.length; i++){
    cartHTML = cartHTML + "<tr><td>" + item[i] + "</td>";
    cartHTML = cartHTML + "<td>$" + price[i] + "</td>";
    cartHTML = "<td>"+ qty[i]+"</td>";
    var cost = price[i]*qty[i];
    cartHTML = cartHTML + "<td>$"+cost+"</td>";
    subtotal += cost;
}
var shipCost = Math.round(subtotal*0.05);
var orderTotal = subtotal + shipCost;
shipCost += ".00";

cartHTML += "</tbody><tfoot><tr><td colspan= '3'>Subtotal</td><td>$"+subtotal+"</td></tr>";
cartHTML += "<tr><td colspan='3'>Shipping*</td><td>$"+shipCost+"</td></tr>";
cartHTML += "<tr><td colspan= '3'>Total</td><td>$"+orderTotal+"</td></tr></tfoot></table>";
document.getElementById("cart").innerHTML=cartHTML;

var now = new Date();
var shipDays = now.getDate()+3;
now.setDate(shipDays);

document.getElementById("sdate").innerHTML = "*Orders placed today will be shipped by" + now.toLocaleDateString();

Hi, just to a quick glance, but you are targeting the ID "sdate" but have no elements with the ID of "sdate". It is not able to add this HTML because it can't find an element to add it to.
