Creating a Shopping Cart
I am making a shopping cart. I have to data master. One has a product and the other includes the items added to cart. The problem is when I add the same item to cart, a new row is created but I want it to be added to the previous one. I have used conditions withe Filter and Has function but it does not work!
When name (in cart data master) HAS input_value (product name in product data master) the row is modified else a new row is created.
Also I have tried the above condition with Filter function. It didn't work similarly!
