Finally I found my problem, What have I had forget ?
From ... How to make a Platform game
"To make the player flash, select the player and add the Flash behavior. Remember to select the actual player, not the PlayerBox object (since it is the visible player we want to flash). We'll use the 'Flash' action from this behavior in a moment."
I didnt add the Flash behavior to "PlayerImages" before to add the action!!! thats why I couldnt find. <img src="smileys/smiley17.gif" border="0" align="middle" />
