Cannot Read property addEventListener of undefined?

JavaScript
1 
var removeButton = document.getElementsByClassName('remove-btn')
  console.log(removeButton)
for(var i = 0; i <= removeButton.length; i++){
  var button = removeButton[i]
  button.addEventListener('click',function(event) {
    console.log('clicked')
      var buttonClicked = event.target
    buttonClicked.parentElement.parentElement.remove()
  })
}

What does your HTML look like?

<div class="order-col">
								<div><strong>Product Total</strong></div>
							</div>
							<div class="order-products">
								<div class="order-col">
									<div>item1</div>
										<img src="products/fig.jpg" alt=""><br>
										<button type="button" name="button" class="remove-btn">Remove</button>
									<div>$980.00</div>

this is my html

Js isn’t my strongpoint but shouldn’t you be looking for less than and not less than or equal to in your loop. Your loop starts at zero.

e.g.

for(var i = 0; i < removeButton.length; i++)
