Can you also build this door in the Pocket Edition?

I tried to recreate this door in Minecraft. I also built it exactly like in the video. Still, it doesn't work. Maybe that's because I'm using Minecraft's Pocket Edition?

Are there Tedstone torches in the building? If so, then it doesn't work. Redstone torches do not have all functions in the Pocket Edition.

No, that's without redstone torches

Ah, I just remembered that the pistons in the Pocket Edition are a little different than in the Java Edition. Are you building this world in a survival world with success or are you allowed to add a few blocks that are not available in survival mode and with which you can open the door without a piston? If you play without success then I could help you.
