SCORE VARIABLE

You should never use a const keyword to declare a variable that will change. The const keyword means = constant, which means whatever value you give to that will stay the same and never change. An alternative to this is the let keyword which can change and is what you should use in this case. So here is an example:

let saleValue = 0; // starts with a 0 value until some values are added to it

let firstSale = 5; 
let secondSale = 15;

saleValue = firstSale + secondSale; 

alert(saleValue); // this line will show a box on screen with the final value

Thanks for replying, alright got it yes, no const for this,... now say that you're getting the sale price from an input in html, like this:

let productPrice = document.getElementById('priceinput') // this points to a text input field in HTML

so... everytime there is a new sale, it is the same variable, productPrice that gets the new value of the new sale... so... if the current score is 100 and the new sale is 200 the result im looking for is that variable to hold now a value of 300,...values can't be gathered statically as in your example aboive since what im trying to do is dinamically update that value,...

Instead what's happening is everytime a new sale comes along the value of the variable gets refreshed to the new sale's value, not really keeping the sales's score.,... check my code please, thanks:

saveButton.addEventListener('click', () => { console.log('HELLO'); const productList = document.getElementById('productField'); let productprice = document.getElementById('productPriceField') const productListdisplay = productList.value; const displayNewLi = document.createElement('li'); displayNewLi.setAttribute('class', 'totalsalestest') let salesScore = parseInt(productprice.value);// THIS IS ME TRYING TO DO WHAT I EXPLAINED ABOVE displayNewLi.textContent = newSaleInput.value + " " + productListdisplay + " $ " + productprice.value; totalSales.appendChild(displayNewLi); existingSalesUl.removeChild(newLi); console.log(salesScore);

});

Really appreciate the help... thanks
