UIScrollView not scrolling programmatically in iOS 6 & 7 both - ios

Question

For testing purpose I have create project where I have two scrollview. First scrollview have images that I inserted manually and in second scrollview I have list of buttons (as menu).
I have button as right and left to scroll UIScrollView programmatically.
After clicking this button I was moving scrollview by setting content size.
myCounter.text = [NSString stringWithFormat:#"%d", [myCounter.text intValue] - 1];
CGRect page = CGRectMake(320*([myCounter.text intValue] ), 230, 320, 150);
[myScrollView scrollRectToVisible:page animated:YES];
CGRect page2 = CGRectMake(320*([myCounter.text intValue] ), 20, 320, 200);
[firstScrollView scrollRectToVisible:page2 animated:YES];
The problem I am facing is only first scroll view is getting scrolled but not the second one.
I am really confused why this is happening.
I am also attaching same project at dropbox as code is little more.

I have downloaded your code and modify the code below, your "page.origin.y is out of the contentSize.height"
- (IBAction)goToLeft:(id)sender {
myCounter.text = [NSString stringWithFormat:#"%d", [myCounter.text intValue] - 1];
CGRect page = CGRectMake(320*([myCounter.text intValue] ), 0, 320, 150);
[myScrollView scrollRectToVisible:page animated:YES];
CGRect page2 = CGRectMake(320*([myCounter.text intValue] ), 0, 320, 200);
[firstScrollView scrollRectToVisible:page2 animated:YES];
NSLog(#"myCounter.text==%d", 320*([myCounter.text intValue]));
}
- (IBAction)goToRight:(id)sender {
myCounter.text = [NSString stringWithFormat:#"%d", [myCounter.text intValue] + 1];
CGRect page = CGRectMake(320*([myCounter.text intValue] ), 0, 320, 150);
[myScrollView scrollRectToVisible:page animated:YES];
CGRect page2 = CGRectMake(320*([myCounter.text intValue] ), 0, 320, 200);
[firstScrollView scrollRectToVisible:page2 animated:YES];
NSLog(#"myCounter.text==%d", 320*([myCounter.text intValue]));
}

Hey mate please set the contentSize of the scrollview in your viewDidLoad method.
[myScrollView setContentSize:CGSizeMake(320*3,200)];
Thanks and have a blessed day
