'colorchooser' undeclared

Okay so I'm super brand new to cocoa and I have one failed thing. It says 'colorchooser' undeclared on the first (colorchooser.selectedSegmentIndex == 0)I have no idea what's wrong!

@implementation Flashbox2ViewController
@synthesize colorChooser, sampleText;

-(IBAction) colorChanged {
    if (colorchooser.selectedSegmentIndex == 0) sampleText.textColor = [UIColor blackColor];
    if (colorchooser.selectedSegmentIndex == 1) sampleText.textColor = [UIColor blueColor];
    if (colorchooser.selectedSegmentIndex == 2) sampleText.textColor =开发者_运维知识库 [UIColor redColor];
}

choose colorchooser or colorChooser

If you are making a @property of colorChooser and @synthesize it... then it is obvious that you should use colorChooser.selectedSegmentIndex and not colorchooser.selectedSegmentIndex...
