Animating Panels

My previous question was solved. My problem now is I'm animating panels using the Unity GUI sliding one off to the right onclick and moving one in from the left. Then on the new panel onclick it will reverse the animations.

The problem is, when I hit Play the animations are in constant loop going back and forth and I can't do anything on the forms. Basically I need to get them to stop going back and forth and then to do the Onclick event.

The animations Loop option are unchecked.
