Well, my problem is that whenever I select the button (or
anything else) I want to give an action to, I open up the
ActionScript window, but it says "current selection cannot have
action applied to it."
The only thing that I can apply an action to is the frame
Using actionscript 2 or 3, you should not be attaching any
code to an
object. You should be writing your actionscript to a frame
space or to
an external .as file. Flash CS3 using AS3 will not allow you
actions to objects on the stage.
