Linking Button to a controller

Hi, i have created a controller in order to punchout for personalisation.

I Have placed this code in the ShoppingCartController :

Extensions.PunchOut punchOut = new Extensions.PunchOut();

            bool isPunchOut = true;
            string id = productVariant.Sku;        // this is the sku
            string ticketId = null;

            if (isPunchOut)
            {
                ticketId = punchOut.CreatePunchOutReference(id,Url,Request);

                // save the reference from punch out into a custom attribute
                // which is saved in the basket item
                var attribute = new ProductVariantAttribute();
                int punchOutAttributeId;
                Int32.TryParse(ConfigurationManager.AppSettings["PunchOutAttributeId"], out punchOutAttributeId);
                attribute.Id = punchOutAttributeId;
                // add this to the product attributes
                attributes = _productAttributeParser.AddProductAttribute(selectedAttributes,
                    attribute, ticketId);
            }

            //save item
            var cartType = (ShoppingCartType)shoppingCartTypeId;
            addToCartWarnings.AddRange(_shoppingCartService.AddToCart(_workContext.CurrentCustomer,
                productVariant, cartType, attributes, customerEnteredPriceConverted, quantity, true));

i wish to link this controller to a personalize button that i have created.


I am new to MVC so i do not quite understand linking views to controllers.


Many thanks
