Basic application

Hey, I’m trying to develop an application in flash for the first time, so you’ll probably find me posting small questions bit by bit over the next few days. First thing which I couldn’t find the answer to on the forums: I want to be able to take the value/item selected from a drop down list, and then when the ‘add’ button is selected for that item to be added to a list. If anyone can tell me how to do this or point me in the right direction that would be great. Also, I want to be able to output the number of items in that list as a variable to be used in the program, but that would be a bonus if you can answer both :wink:
