Actionscript 3 - 1120 error

An error 1120 is ‘Access of undefined property’ which can means two things. Firstly, you are trying to access an undefined variable, and secondly you have not given a correct instance name to a movie clip or button.

To solve this problem you need to make sure the instance name field is not empty and contains a valid instance name with correct spelling.




You also need to make sure you make the correct reference to the instance name as shown below.

myMovieClip.addEventListener(MouseEvent.CLICK, test);

This should solve an 1120 AS3 error.
