Problem with spritetesheet

[jsalinas]

Hello, I've just started using this framework and it's fantastic, but I'm having a problem with the spritesheet function - I'm getting this error when I try to add a new spritesheet:

Phaser.AnimationParser.spriteSheet: width/height zero or width/height < given frameWidth/frameHeight

And the image is not showing on the game:

 

 

 

This is how I'm adding the spritesheet:

game.load.spritesheet('kamel', 'assets/sprite_kamel.png', 40, 69);

The image is 274x69.

 

Am I doing something wrong?

 

Thanks.

how many frames is there? 

The X/Y needs to be pretty exact to work. 

i believe the width setting is wrong because you're declaring a width of 40 but the image alone is 274. How do you get 40 out of 274?
