Add to cart for catalog ad on Facebook

I want to know if my understanding is right.
I want to run catalog ad on Facebook so I have installed the 3 event pixels (view content, add to cart, purchase)
But since there is no separate page for add to cart, I set up in a way that when user click on "add to cart" then, event code "add to cart" will be activated. (When on viewcontent page, I can see 4 pixels (pageview, viewcontent, addtocart, addtowishlist) but add to cart and purchase are shown as red. Then, When I clicked on cart button, After that, add to cart button becomes activated. (pixel helper) enter image description here
So I believe pixel have been installed correctly. But in my product feed Diagnostics in business manager, it shows as something like this.
Is there any way that I can fix the issue?
Thanks!

A simple Checkout Button?

I am using the simple paypal-provided HTML buttons, with 'add to cart' buttons.
Does anyone know the simple code to send the user to the checkout page?
For instance, a user has added an item to their cart, then clicked on the continue shopping button, how do they return to this cart page and/or checkout page without adding another item?
Thanks!
When you create a standard shopping cart button with PayPal you get 2 code snippets back. One is for the cart button and the other is for a View Cart button. You would need to make sure and place the View Cart button somewhere on the page so that users can bring that back up without adding an item.

multiple instances of a viewController to reference in a different viewController

I have a viewController which takes details of a product and calculates the price.
The User can calculate the price and add that product to cart. Here I was simply adding self to the array defined in cart.h and user can continue to be on the same screen, calculate price for another product and add to cart. If I have added 3 different products to the cart, in the cartViewController I see 3 products added, but the details of all the 3 products is the same(i.e. details of the 3rd products are shown)
Is there any way by which I can keep track of what product I am adding?
Thanks in advance for your help.
Details :
I have a product screen. There are 5 textfields which take in values and calculate final price. User can tap "Add to Cart" to add the details of this product to the cart and continue on the same screen to find the price of next product by changing the textfield values. Once again the user taps on "Add to Cart" to add details of the new product and so on. When user taps of "View Cart" he should see all the products he had added, but I see only the last product added multiple times, i.e. every time I add a new product, it overwrites the previous products as well. So, as a result I am only able to see the last product the no.of times I tapped "Add to Cart"
Please help.
You're probably using an instance variable to build the cart item and adding it to the array. Then you're editing it and adding it again. And again.
You should be creating a new cart item each time and adding the new item. Then you won't edit it the next time the button is tapped.
Never mind, I found a workaround for it.
I am creating a model class and creating a new instance of that class every time I need to add an instance of the viewController to the array.
May be it is not the optimum way but it is working for me.
