Ok, so I'm trying to get an image to slide across the screen. (its actually like a metallic glow going across letters). So I have two frames. In the first frame, I have the glow to the left of the letters, and in the 2nd, the glow is to the right. So then I hit tween to tween it, and it doesnt change anything. So i go back, and realize that the glow in the first frame is in the same spot as in the 2nd. How can I get this tween/slide deal to work again?

If this is hard to understand, let me know, and I can try and work it out easier.
