Can't withdraw CGPoint Values from A mutableArray of NSValue
===

I made an NSMUtableArray of CGpoints and I stored them by subclassing as NSValue, but I cant get the values out. here I what I did.

     CGPoint graphPoint;
        NSMutableArray *pointValues = [[NSMutableArray alloc] init];
    
        for( int x =0;x<5; x++)
        {
        NSDictionary* xValue = [NSDictionary dictionaryWithObject:[NSNumber numberWithInt:x] forKey:@"X"];
        graphPoint.x =x;
        graphPoint.y = [CalculatorBrain runProgram: self.graphingPoint usingVariableValues:xValue];
        
        [pointValues addObject:[NSValue valueWithCGPoint:graphPoint]];
          
    }

I tried using this to get the values but I just get null back

 
    for( int x=0; x<5; x++) {
    NSValue *val = [pointValues objectAtIndex:x];
    CGPoint point = [val CGpointValue];
    NSLog(@"Points = %@", point);
    }
