Generating a URL string for NSURLRequest fails to initiate

This one has me pretty confused. If I put in the following:

NSString *LoginURLString = [NSString stringWithFormat:@"http://dispatch.americantaxi.com:8080/AT/servlet/OnlineOrderServices?command=retrieveCustomerCommonPlaces&customerId=13242134"];
//NSLog output:  http://dispatch.americantaxi.com:8080/AT/servlet/OnlineOrderServices?command=retrieveCustomerCommonPlaces&customerId=2314084

And use this in a URL request, it works fine, but I need to make this dynamic, so I have it concatenate the URL string with a new UserID by using the following: 

NSString *user = [NSString stringWithFormat:@"%@", [[NSUserDefaults standardUserDefaults]stringForKey:@"CustomerID"]];

//user = [[NSUserDefaults standardUserDefaults] stringForKey:@"CustomerID"];

NSString *LoginURLString = [NSString stringWithFormat:@"http://dispatch.americantaxi.com:8080/AT/servlet/OnlineOrderServices?command=retrieveCustomerCommonPlaces&customerId=%@", user];
//NSLog output:  http://dispatch.americantaxi.com:8080/AT/servlet/OnlineOrderServices?command=retrieveCustomerCommonPlaces&customerId=2314084

Here is the rest of my request initializer: 

 NSString *urlString = LoginURLString;
responseData = [NSMutableData data];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];

And the other methods that handle the request:

   -(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
    [responseData setLength:0];
}

-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
    [responseData appendData:data];
}

-(void) connectionDidFinishLoading:(NSURLConnection *)connection{
    //   [connection release];

    CommonPickUpArray = [[NSMutableArray alloc] init];
    CommonLocationInfoArray = [[NSMutableArray alloc] init];

    NSString *data = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];
    NSLog(@"%@", data);
}

This request never even starts. I really don't understand why. I have tried to output the two strings to the NSLog and either way they look exactly the same. Can anyone explain? Thanks for your help!

Edit: The Connection didFailWithError method is outputting this:

Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0xf6a6f50 {NSUnderlyingError=0xf6a75d0 "bad URL", NSLocalizedDescription=bad URL}

Output from answer 1:

2012-05-08 13:45:24.959 AmericanTaxi[1295:707] Connection failed with error: bad URL 2012-05-08 13:45:24.960 AmericanTaxi[1295:707] for the URL: (null)

Output of urlString and LoginURLString:

2012-05-08 13:57:40.415 AmericanTaxi[1320:707] LoginURLString: http://dispatch.americantaxi.com:8080/AT/servlet/OnlineOrderServices?command=retrieveCustomerCommonPlaces&customerId=2314084

2012-05-08 13:57:40.417 AmericanTaxi[1320:707] urlstring: http://dispatch.americantaxi.com:8080/AT/servlet/OnlineOrderServices?command=retrieveCustomerCommonPlaces&customerId=2314084

In your didFailWithError, check the URL and see why it is bad by adding this to your didFailWithError delegate:

NSLog(@"Connection failed with error: %@", [error localizedDescription]);
NSLog(@"for the URL: %@", [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]);

Post the result.
