ActionScript 2.0 Fixing an existing FLA/SWF

YOU MUST BE ABLE TO FIX OTHERS WORK This project is to bug fix an already existing SWF file. The code is in ActionScript 2.0. A short explination of the situation. There are 2 primary files. 1. A Canvas (loads everything else and has the background colors) 2. A buttons files (loads activities and interactive content) The buttons file has a warning on it which tracks what the user is doing. 1 of 3 things can happen: 1. User is in an activity loaded on a different layer and click on a different activity button. A warning presents itself. They can move forward or go back to the current activity. 2. User is in content nothing happens clicks on a different button, no warning or message appears. 3. User is in an activity and clicks on "content" the activity gets placed in the background and a "back to activity" button appears. We have an example of the buttons working correctly and the current version which is not. There is a slight difference between the two (10 lines of added code). A NDA will need to be signed and we will also need you to sign a form saying that we will own any content you have completed for us. (attached) I will also provide the working and non-working versions of the file after the project is accepted. (Attached)
