Hi there

Honoustly, I dont know what im doing wrong,

I create the new file, bring the graphic into stage, make it a graphic, right click on e.g. frame 20, create keyframe, click on frame 1, click on the graphic, goto alpha and make in 0%, click on frame 20, click on the graphic, make it e.g. 100% alpha, right click between frame 1 and 20, and click on motion tween. There is no tween anywhere, what am i doing wrong?

Attaching the flash.fla file, hope you can help

Hi nVee, glad to have you here.
The reason you are having this issue is because you are using the new motion tween which can be tacky to use for noob.
To solve your problem, you have to delete the last frame and keep the frame indicator at the last frame. Then select the symbol on the stage. Change the alpha setting under the property panel from there. Now when you scroll the frames, you will see it fade in.
