MFMailComposeViewController confusion

I recently learned how to implement an email in an iOS app, and I am confused on what this means. I have attached the errors, and the code as well. What I am trying to do is have the user enter information into a UITextField and when they press send, it will send to my email. I have gotten these errors for the past couple times I have ran it, and I am still confused. Thank you in advance!

    Information:Information:Building target 'RPSS' from 'RPSS' with configuration 'Debug' for architecture 'i386' using 'Simulator - iOS 4.3' sdk
    Error:Error:The following build commands failed:
    Error:Error:RPSS:

code:

-(void) showEmailModalView {
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;// <- very important step if you want feedbacks on what the user did with your email sheet

    [picker setSubject:@"Comments, Suggestions, Etc."];

    // Fill out the email body text
    NSString *emailBody = [NSString stringWithFormat: @"%@", supportInput.text];

    [picker setMessageBody:emailBody isHTML:YES]; // depends. Mostly YES, unless you want to send it as plain text (boring)

    picker.navigationBar.barStyle = UIBarStyleDefault; // choose your style, unfortunately, Translucent colors behave quirky.

    [self presentModalViewController:picker animated:YES];
    [picker release];
 }

 - (void)mailComposeController:(MFMailComposeViewController*)controller     didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    if (result == MFMailComposeResultSent) {
        UIAlertView *sentMail = [[UIAlertView alloc] initWithTitle: @"Mail Sent:" message: @"Your mail has been sent!" delegate: self cancelButtonTitle: nil otherButtonTitles: @"Close", nil];
        [sentMail show];
        [sentMail release];
    }

    [self dismissModalViewControllerAnimated:YES];
}

-(IBAction) send : (id) sender {
    // We must always check whether the current device is configured for sending emails
    if ([MFMailComposeViewController canSendMail]) {
        [self showEmailModalView];
    }
    else {
        UIAlertView *a = [[UIAlertView alloc] initWithTitle: @"Error" message: @"Device not configured to send mail." delegate: self cancelButtonTitle: nil otherButtonTitles: @"Ok", nil];
        [a show];
        [a release];
     }
}

You need to include the MessageUI framework. Have a look at How to "add existing frameworks" in Xcode 4?
