No problem - I'm glad it works!
The code had three problems: AnimTo was 2 instead of 3, and the Tile Height value was way too much for the spritesheet (I'm sure it wasn't 75px high, perhaps you mixed up height and width... I do that sometimes too). The width was also a bit more than 1/4th of the spritesheet width.
The spritesheet was not aligned well and there was too much space between each sprite. I've cut the sprites up in Fireworks, aligned them on top of each other, tested the animation and then made a new sheet by stacking the frames left-to-right with no space in between.
