A small flash Interactive

I need help with a very small project. I need to build a simpler version of the widget like the one shown on [login to view URL] Attached is a flash file and an excel file. I will provide the sound files on project start. There are 5 buttons in the attached fla. Each button's on and off state needs to be tracked and depending on the state of the buttons one of the sound files needs to be played. Although there can be a total of 2^5 = 32 combinations but we need to track only 9 and for all the rest no action is to be taken. The excel file lists out the 9 combinations and their corresponding sound files. For each of these combinations a message (given in the excel file) also needs to be displayed in the dynamic text box. Of the 9 combinations, in 4 cases the state of the last button needs to be switched back to off once the sound file is done playing. This sound also has to change accordingly. Lastly, please ensure that one cannot select step 2 until step 1 has been completed and step 3 until both step 2 and step 1 have been completed
