Can't get the animation to trigger while the player is moving

I have attached an animator to my Player object and the animations work as intended except that the Player moves physically first before the 'jump' animation. I am working on a grid based system so I want it to look as if the player is jumping onto another block. I have tried rearranging the order of the animation and the player movement but to no avail. I am using a trigger to initiate the animation movement.

 animator.SetTrigger ("Scrapper_Move");
 AttemptMove<Wall> (horizontal, vertical);

 

Any advice would be appreciated.
