line 1: W:26.6 H:53.6 X:13.3 Y:41.3 line 2: W:16.5 H:14.5 X:34.9 Y:7.3 line 3: W:5.8 H:14.4 X:46.0 Y:7.2 line 4: W:17.6 H:35.5 X:40.2 Y:32.1 line 5: W:22.1 H:0.1 X:20.2 Y:49.9 and then fill it in. Go back to Scene 1. Place one fireworkbase at the following places: X:20.0 Y:394.2 . Create a keyframe(F6) on the 17th frame and move the movie clip to X:303.5 & Y:227.6 . Now make it a motion tween by clicking on any frame before no.17 and select motion from the tween menu.
