cart

  simplecart({ checkout: {   type: "paypal",   email: "you@yours.com" }, cartcolumns: [      {view:'image' , attr:'thumb', label: false},     { attr: "price" , label: "price", view: 'currency' } ,      { attr: "quantity" , label: "qty" } ,      { attr: "total" , label: "subtotal", view: 'currency' } ,     { view: "remove" , text: "remove" , label: false } ], cartstyle: "table" });
