I want to users can add product to cart without regestration. I believe variables are a good fit for this purpose but i cant create action that adding +1 item from collection list to variable by clik on button into collection item. There is no quantity,one item can only be purchased in one copy, so i want just add and delete products from cart and be able to display this products in cart and use them for checkout. Please help me to solve this issue. I would really appreciate your help and any advice you can offer. Thank you in advance for your time and effort! ---

There are many ways to do this. [this](https://community.weweb.io/t/add-to-cart-button/866/2) is one example (it’s with quantities but it’s the same principle) Another simple way would be to have an array as variable to keep track of the products, and then use [array functions](https://docs.weweb.io/formulas/array.html) to add/remove a product. Keep in mind that in this case you want to store a simple value like a string in the array. ---

I am trying to do it the array way, but only one product is displayed. Could you suggest what I’m doing wrong? Uploading: Screenshot\_1.png… Uploading: Screenshot\_2.png… Uploading: Screenshot\_3.png… Uploading: Screenshot\_4.png… Uploading: Screenshot\_85.png… ---

The simplest way of doying this, if you don’t need quantities, is, as I said, an array of ids (strings). It looks like you are creating an array of arrays of strings. To add a product insert the id at the beginning. To remove a product replace the whole array and use the “remove” function as described in the docs. In the end you want something like `["prod-id-1","prod-id-2"]` and use the id to lookup the product data.
