As mentioned in the video. You need to implement a method called buttonPressed that returns IBAction.

- (IBAction) buttonPressed {
   // task 2 code will go inside this method

}

No need to apologize. It's always confusing and scary when you are learning something new, which is why we have the forum. In the video when you created the IBAction the method was created for your within the .h and the .m files. In the code challenge you are asked to write out the method manually. The name of the method is buttonPressed. What I wrote above is the answer for task 1.

For task 2 you are asked to assign a string to the label property named quoteLabel.

- (IBAction) buttonPressed {
self.quoteLabel.text = @"The road to success is always under construction";
}

If you are getting confused with the syntax and language then I highly recommend taking our [Objective-C Basics](https://teamtreehouse.com/library/objectivec-basics) and then you can come back do this course.

I think ui causes some confusion because when you hit preview with the correct method skeleton built, it will kick back an error:

If I say 'Check Work' it will accept it.
