You need to get out of the pokemon stats screen & on to the battle screen where you see you & your opponent's pokemon on the bottom left & upper right side of the screen respectively first of all, then after that, just click on fight & pick & move, simple as that...
The only reason you would see the stats for the move is that you clicked on pokemon & then picked 1 & then picked summery & then picked check moves
& then picked an attack for some reason

...
If you are having a problem playing a game, for crying out loud, please, please just read the instruction booklet that comes with it in case you haven't done this, alot of people don't for some reason...
I believe there is a place to post questions to avoid topics like this but I won't go any further into that...
Pay more attention to what you are doing cause if you were, this in no way would have happened, it's not too hard to learn, alright?...
