iOS HELP Receiver is a forward class and corresponding @interface may not exist

[codermon]

thanks for taking the time to read my problem and help me

I am building a TabView project and on tab 3 of the app I have a row of albums, in album 3, page 1 the nextButton takes the user to page 2 of the album. Page 2 has more buttons, including a backPage(get back to page 1) and a backButton(to go back to the album selection page).

ERROR:

    A3Page2ViewController.m:92:49: Property 'view' cannot be found in forward class object 'A3Page1ViewController'

WARNING:

    A3Page2ViewController.m:91:28: Receiver 'A3Page1ViewController' is a forward class and corresponding @interface may not exist

I have searched this site and others and most of the answers are in relation to how @Class should be used in the header filw and #import ".h" should only be used in the .m file. I have checked my code and I was following the rules, so why does it still not work?

THIS IS WHAT I HAVE DONE: This is the function(in A3Page2ViewController) that is apparently making the error...

    -(IBAction)backPage:(id)sender
    {
    	a3Page1ViewController = [[A3Page1ViewController alloc]initWithNibName:@"A3Page1ViewController"bundle:nil];
        [self.view addSubview:a3Page1ViewController.view];
        
    }

**Please note that when commented out, the app runs FINE all the views are loaded, all buttons including backButton work. When uncommented it just refuses to build, with the errors.**


Below I list both A3Page1ViewController and A3Page2ViewController both the .h and .m files.

You can see that I have the @class and #import ".h" in the correct places.

WEIRDNESS!!
I actually have the exact same code WORKING in the 2nd tab, I use it to switch between views with out any problem. SO WHY DOES IT NOT WORK HERE?!?!

**PLEASE HELP I AM STUCK ATM AND I DON'T KNOW WHY:/**
