when i make a frame and then i create another frame, the 2nd frame and the 1st frame look the same even though i made edits in the 2nd frame.
Are you drawing inside a symbol on the stage?
Change on the timeline can only occur in keyframes. The first frame in any layer is a keyframe. If you add frames, then the content of those additional frames will be the same as the first keyframe. If you edit the art in any frame after a keyframe, you are actually editing the art at the keyframe. To show change, create a new keyframe and make the change at that second keyframe. Look at the tutorials that come with Flash for more information on basic animation.
