Help with string format. Getting error: 'Use of undeclared identifier"

I am playing around with web services and can't get my string format correct for my SOAP request. I can't seem to get @%d to format correctly.

Here's my code: 

 NSString *sSOAPMessage =[NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                                            "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
                                                        "<soap:Body>"
                                                        "<postScore xmlns=\"http://tempuri.org\">"
                                                        "<score>"@"%d""</score>"
                                                        "<name>"@"%d""</name>"
                                                        "</postScore>"
                                                       "</soap:Body>"
                                                       "</soap:Envelope>",scoreInt,nameString] ;

if nameString is a string then you need to use %@, not %d. %d is for integers, %@ is for objects such as strings.

NSString *sSOAPMessage =[NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                                            "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
                                                        "<soap:Body>"
                                                        "<postScore xmlns=\"http://tempuri.org\">"
                                                        "<score>"@"%d""</score>"
                                                        "<name>"@"%@""</name>"
                                                        "</postScore>"
                                                       "</soap:Body>"
                                                       "</soap:Envelope>",scoreInt,nameString] ;
