ExecuteAppend and ExecutePrepend methods on .Net documentation has error in sample code

The code samples below has an error:
http://docs.couchbase.com/couchbase-sdk-net-1.3/index.html

client.ExecuteStore(StoreMode.Set, "beers", "Abbey Ale");
Func<string, byte[]> stringToBytes = (s) => Encoding.Default.GetBytes(s);
var result = client.ExecuteAppend("beers", new ArraySegment<byte>(stringToBytes(",Three Philosophers")));

if (! result.Sucecss)
{
Console.WriteLine("Append failed with message

{0} and status code {1}", result.Message, result.StatusCode);

if (result.Exception == null)
{ throw result.Exception; }
}



client.ExecuteStore(StoreMode.Set, "beers", "Abbey Ale");
Func<string, byte[]> stringToBytes = (s) => Encoding.Default.GetBytes(s);
var result = client.ExecutePrepend("beers", new ArraySegment<byte>(stringToBytes(",Three Philosophers")));

if (! result.Sucecss)
{
Console.WriteLine("Prepend failed with message {0}

and status code

{1}

", result.Message, result.StatusCode);

if (result.Exception == null)

{ throw result.Exception; }

}

the last IF should be:
if (result.Exception != null)
