Motion tween help

[Thomo]

I'm trying to create a motion tween for a movie clip symbol. Never done it before and I'm having problems.

I place the movie clip on frame 20 and key frame. I then key frame at 50 and move the clip to a new position. I click on frame 20 and drag to (and including) frame 50. I right click and select Create Motion Tween. I see an arrow between frames 20 and 50. However when I play the animation the movie clip does not move.

I try with a basic rectangle and it works fine.

What am I doing wrong, please??

When you place the movieClip on frame 20 don't add the key frame. You should only have a key frame on frame 50. Take a look at the attachment.
