Spritesheet working but animation is cutting off on the edges

Hi all, 

I having a hard time getting my spritesheet file dimensions right: 

 - I am using Zwoptex to create the sprite sheet and I must be doing something wrong because for the life of me I can’t see to get the spritesheet animation to work right.  Here’s how it’s looking like once I run the file in the app : http://screencast.com/t/BaDKG1JYw

As you can see, the animation is cutting off on the edges.  I have tried to change the following width and height, but no luck.

Attached is the actual spritesheet file I am using to animate, so you can try it yourself and see.

 local catSheetData = { width =256, height =256, numFrames=3 } 

Any suggestions and help would be highly appreciated at this point, as I have done everything I can to solve this with no luck.  It’s kinda annoying at this point because I have spent so much time trying to create the correct dimensions for the sprite instead of coding… 

Thanks in advance.
