Expected expression error in X code.

Question

Hi i am a newbie to app developing and the objective c language but i  have exhausted all my efforts in trying to find out whats causing this  error my code is as follows:
-(IBAction)back:(id)sender {
    if ([webView canGoBack] == YES)
    {[webView goBack];}    else {
        UIAlertView *alert = [[UIAlertView alloc]  (HERE IS WHERE X CODE DETECTS THE ERROR)
initWithTitle:@"Oops"  message:@"No previous questions!" delegate:<#(id)#>  cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alert show];
-(IBAction)forward:(id)sender {
    if ([webView canGoForward] == YES){
        [webView goForward];}
    else {UIAlertView *alert = [[UIAlertView alloc] (X CODE ALSO DETECTS THE SAME ERROR HERE)
initWithTitle:@"Oops"  message:@"No subsequent searches!" delegate:<#(id)#>  cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alert show];
@end
THANKS

Ignore my last post, just tried it and having that ,nil does not affect the compile.
This compiles with no errors
UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle:@"Oops"  message:@"No previous questions!" delegate:nil  cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
