I've watched the tutorial for animating drawing a curved line (http://www.wonderhowto.com/how-to-animate-pencil-drawing-curved-line-flash-160126/view/) but I can't get past the part where you add the motion tween. When I go to do that, it's greyed out and only "Classic Tween" is available (which doesn't work - won't follow the guide). What am I doing wrong?? My pencil is a jpg file - I've tried dragging it straight from the library and also converting it to a symbol but neither works.
If someone can help me, I would greatly appreciate it - thank you!!
