From where to link the shop?

My last item under Articles is "Default Menu Item (English (UK))" with a select box with all the menus.
Is this the correct option? in this case which is the option I choose?

Hi,
Just choose one. Then it will work. When you test you will see it will work.

I have tried several options and it seems the cart page works but I get any product because the product page the button "add to cart" does not appear

Did you check this:
Please go to Eshop - System - Configuration - Options - Articles
The catalog mode should be set to "No" to have the "Add to cart" button.

This is the configuration of my Articles

It seems to be the correct setting. I don't know the correct solution then, sorry.
For fast response, maybe you can submit a ticket, then Giang will help you.

Sorry, sorry, sorry ... I just realized that the client had created the products but in quantity had "0" and, of course, you can not add to cart a product that there is not one in stock.

Thanks for your great help and apologizes for any inconvenience

No problem. I didn't think of that. Just learned something from you.
But there is one option, that you can add to cart with 0 or negative stock.
See attachment.

Now just want to get to the point of adding products to the cart because the client wants to sell and bill for other routes.
The problem is I do not know if it is saved in the database products are in the shopping cart of a buyer.
You may be saved in a particular table or there is no way to stay registered products in the shopping cart?

I've consulted by ticket but can take up to 24 hours and is a very urgent issue

Hi,

I am not sure, but I think there are two way this can be done:
1) Customer has to create an account and then products will be save to this account.
2) Cookies!. But I am not sure about this.
Maybe you can test with an account? To see what happens?
