Sprite Sheet Animation started by Mouse Click

I have a animated fire sprite. It is set to hidden, another button is set to "show" this sprite when it's clicked.

Problem is that the animation runs while hidden so when you click the button that reveals the sprite, the animation cycle may be complete. It's set to loop but I would like the sprite to start on frame 1 and begin play once you click the button, not autoplay.

Any ideas how to do this?
