Help with Sizes other then small not being added to cart

[Boliye]

Hey There! Facing problem with the option to add sizes other then small to the cart. Like on default I can add the small size to the cart but when I select either medium or large they can’t be added to cart. And when I revert back to select small again, I can’t even add that to cart. Attaching images below to clear out what I am saying

That’s because after switching the size button, your code reported an error, which resulted in the subsequent code not being executed.

Hopefully it will help you. If yes then Please don’t forget hit Like and Mark it as solution!

Greetings Anne! Thank you for finding the error. I saw your reply but can’t find how you fixed it. Please if you could tell me what to do or what to edit to solve this problem? Thanks a lot!

The inventoryVisibility dom was not found in the above code. You need to know why this dom does not exist. If you need to avoid this error, you can add a non null check. Just like:

if (inventoryVisibility) {
     inventoryVisibility.classList.remove('visibility-hidden');
}
