I'm having difficulty understanding exactly what you are trying to accomplish.
If you are trying to have the text visible in each frame, you have to bring up the animation timeline.
Once you bring up the timeline click on a frame and look at the layers pallete. Make sure the text layer that you added is visible [there will be an eye icon].
Select the next frame, make sure it is still visible. You can do this frame by frame, or select all the frames and then change the text layer's visibility.
If that is not exactly what you're trying to do, can you post some pictures and more information of what you're working on so we can better understand.
