Now in our Flash file, which I named "states.fla", we'll start off adding (2) layers, "actions" and "combBox"

layer setup


Next, hit Ctrl+F7 or go to Windows->Components to bring up the Components Panel. Make sure the "comboBox" layer is selected and drag a comboBox onto the stage.

add combo


And don't forget to give it an instance name. I chose "cmbState"

name it


That's it for the stage. Now we can move on to the Actionscript...
