Launch it with the debugger and check the stack when it crash.Without any hint about the stack, we cannot really help you, but just give you some guess.

See code below. Get a error of “EXC_BAD_ACCESS” when I make entries in the GUI. Code used to work with no problems. It appears that it is doing an illegal substraction, which I think means the objects are not being initialized with a value of 0. At least that is my guess.#import "MonthlyReport.h" @implementation MonthlyReport + (void)initialize { if (self == [MonthlyReport class]) {NSArray *keys = [NSArray arrayWithObjects: @"reportCumActualCost", @"reportActualCost", @"reportPredictedCost", @"reportCumPredictedCost", @"reportCumlativeInvoiceTotal", @"reportMonthlyInvoiceAmount", nil]; [self setKeys:keys triggerChangeNotificationsForDependentKey:@"reportCumDifference"]; [self setKeys:keys triggerChangeNotificationsForDependentKey:@"reportCurrentDifference"]; [self setKeys:keys triggerChangeNotificationsForDependentKey :@"reportPercentDifferenceMonth"]; [self setKeys:keys triggerChangeNotificationsForDependentKey :@"reportPercentDifferenceCum"]; [self setKeys:keys triggerChangeNotificationsForDependentKey :@"reportInvoiceMonthlyDifference"]; [self setKeys:keys triggerChangeNotificationsForDependentKey :@"reportInvoiceCumlativeDifference"];} } //Calculate differences - (NSDecimalNumber *)reportCurrentDifference; {return [[self valueForKey:@"reportActualCost"] decimalNumberBySubtracting: [self valueForKey:@"reportPredictedCost"]];} - (NSDecimalNumber *)reportCumDifference; {return [[self valueForKey:@"reportCumActualCost"] decimalNumberBySubtracting: [self valueForKey:@"reportCumPredictedCost"]];} - (NSDecimalNumber *)reportInvoiceMonthlyDifference; {return [[self valueForKey:@"reportMonthlyInvoiceAmount"] decimalNumberBySubtracting:[self valueForKey:@"reportActualCost"]];} - (NSDecimalNumber *)reportInvoiceCumlativeDifference; {return [[self valueForKey:@"reportCumlativeInvoiceTotal"] decimalNumberBySubtracting:[self valueForKey:@"reportCumActualCost"]];} //Calculate percents - (NSDecimalNumber *)reportPercentDifferenceMonth; {return [[[self valueForKey:@"reportCurrentDifference"] decimalNumberByDividingBy: [self valueForKey:@"reportPredictedCost"]] decimalNumberByMultiplyingByPowerOf10: (short)2];} - (NSDecimalNumber *)reportPercentDifferenceCum; {return [[[self valueForKey:@"reportCumDifference"] decimalNumberByDividingBy: [self valueForKey:@"reportCumPredictedCost"]] decimalNumberByMultiplyingByPowerOf10: (short)2];} @end _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
