Hi,
I have recently begun working on this video project and i have come to a point where i don't know how to do something. I have a video where it is like 3 screens and it sweeps from left to right then back to the middle. What i want to know how to do is how do i put other videos i have to fit those screens and to have them stay with the sweeping of the screen. Any help would be appreciated. BTW this is in adobe after effects.

No this are 3 screens in the video shot.
the video is like this. It starts with just one screen showing in the room then it pans to the right sweeping over a tv in the middle and go to the far right one and then it pans back to the middle one and zooms out to show all 3.

I will assume you already have the animation of the screens completed. However, it's still difficult to say what you should do next as I am unsure as to whether you have animated using a camera that is moving in 3D space, or you are simply animating the screens' position properties to budge them in and out of the visible comp area.
If you are animating screen position, you should consider using a camera instead.
The reason I'm thinking you might be animating screen position is that, if you were using a camera, you would not have to worry about making your footage "stay in the screen" when the screen moves. The footage would share much the same position as the screen, and this wouldn't change when the camera moved.
However, if you have the animation just as you want it, place the footage beneath the screen in the layer stack, use the pen tool to draw a mask around the edges of the screen if the screen is not already transparent, set the mask to "subtract", position the footage how you want it, then parent the footage to the screen. When the screen moves, the footage will move with it.
Also remember to turn on motion blur for all your layers and for the comp.

And what will REALLY help is to actually put some thought into your finished effects shot before you go to shoot it. Ask questions on how the shot may (or may not) be accomplished!
When you're out on a shoot, and you say, "we'll fix this in post" without knowing PRECISELY HOW you're going to fix it in post, don't shoot it! You'll only end up shooting it over again.
