    I'm quite new to objective-C and come from Java and C++, so I am not too comfortable with the NSAutoreleasePool yet (if this is related to that). The error I'm getting is EXC_BAD_ACCESS. Anyway:
    Code:
    myController.h:
    
    #import <Cocoa/Cocoa.h>
    @interface myController : NSObject {
        IBOutlet NSButton *PlayPauseLabel;
    	
    	// Script stuff
    	NSAppleScript* getPlayerStateScript;
    	
    	NSString* playerState;
    }
    - (IBAction)backPress:(id)sender;
    - (IBAction)forwPress:(id)sender;
    - (IBAction)plPaPress:(id)sender;
    @end
    
    
    myController.m:
    
    #import "myController.h"
    
    @implementation myController
    
    - (void)awakeFromNib {
    	getPlayerStateScript = [[NSAppleScript alloc] initWithSource:[NSString stringWithFormat:@"tell application\"iTunes\"\n return player state as string\n end tell"]];	
    	playerState = [[getPlayerStateScript executeAndReturnError:nil] stringValue];
    	
    	NSLog (@"%@", playerState); // This works
    }
    
    - (IBAction)backPress:(id)sender {
    	NSLog (@"%@", playerState); // This doesn't work
    }
    ...
    
    
    Any help would be greatly appreciated
