Animating sprite resets its transform position after being moved

Hi folks. I'm using transform.Translate(Vector3.up * variable); to move an AnimatingSprite object in world coordinates. The object is part of the Orthello 2D framework. The sprite animates through 8 images that I've published into a cocos2D sprite atlas.

My JS code is written so that when I press the space bar ("Jump") the sprite moves (+m,0,0). However every time the sprite has moved in one frame, the next frame sees the sprite reset back to its initial coordinates (0,0,0). My sprite is being one stubborn fellow!

I thought this might have to do with the animation script, but I don't know Orthello 2D well enough to understand how it cycles through the sprite atlas images.

Do I need to tell the sprite something else in order for it to remain at its newly translated coordinates? Should I make a new function that isn't Update to handle this?

JavaScript - my sprite moving code

 var m : float = 1;
 var obj : Transform;
 
 function Update () 
 {
     if(Input.GetButton("Jump"))
     {
         obj.transform.Translate(Vector3.up*m);    
     }
 }
