Water Temple Issue, Seriously

[dubbed]

Ok well I've encountered a huge problem. Basically when I get to the water temple, I have to get something out of this room. I have to move a block that I moved previously to get what I'm guessing is a key. Well problem is I can't move the block. I've already positioned it from the beginning when I started it and even went back and checked it was all fine. For some reason this block is not moving. Idk what went wrong, but I know it's the game.
