effects not working (please help)

Hello, i've recently had a problem with after effects in which my effects don't work. I'm not quite sure what the problem is but when i split a photo and add it to another one and preview it, it's fine and works perfectly but i watched a tutorial on a zoom transition and i don't know what i'm doing wrong but when i add transform and motion tile e.t.c it never shows up.

after effects → smooth zoom transitions - YouTube

That is the tutorial i followed. I have the keyframes in the right place and everything but the transition never seems to work, why is this? Someone please help

This is what mine looks like. When i click on a certain part of the video, The transition doesn't work.
