Error message in XCode

I followed a tutorial of XCode and I have got an error message of
error: 'disp_update' undeclared (first use in this function)
May I ask do you know how to solve this? Thanks in advance!!

--CounterController.m

#import "CounterController.h"

@implementation CounterController
- (IBAction)abutton_pushedid)sender {
count++;
[disp_upate setIntValue:count];
}

- (IBAction)mbutton_pushedid)sender {
count--;
[disp_upate setIntValue:count];
}

- (IBAction)pbutton_pushedid)sender {
count+=10;
[disp_upate setIntValue:count];
}
@end

--CounterController.h
#import <Cocoa/Cocoa.h>

@interface CounterController : NSObject{
IBOutlet id disp_update;
int count;
}
- (IBAction)abutton_pushedid)sender;
- (IBAction)mbutton_pushedid)sender;
- (IBAction)pbutton_pushedid)sender;
@end

You misspelled the 'dis_update' member in CounterController.m. In your implementation code you have it spelled as 'dis_upate'.

I am sorry, but I could not see where is the misspell, please advice. Thank you very much.

In your .h file you have declared

IBOutlet id disp_update;

Click to expand...

In your .m file you are attempting to reference this member as

[disp_upate setIntValue:count];

Click to expand...

dis_update and disp_upate are not the same thing. You need to change your .m file to reference

'disp_update'

your missing the 'd'

Oh!!!! Thanks!!
