    var product_price = $(this).closest('tr').find('.calActivitylPrice').text();

        method: "POST",
        data: {
            product_id: product_id,
            product_name: product_name,
            product_price: product_price,
            quantity: quantity
        },
        success: function(data) {
            var obj = JSON.parse(data);

            $(changeToRemoveBTNSec).html('<button type="button" name="remove" class="btn btn-danger remove_inventory" id="' + obj.removebtn + '">Remove</button>');

            $('#totalDetails').html(obj.cart_total);
            $('#totalQty').html(obj.totalQty);
