How to play animation when GUI button is pressed?

Hey everyone, so I'm having some trouble getting an animation to play when i click the play button in the menu. The animation is set on the main camera to move its position to another. Thanks in advance.

     public Animation FTH;

 void MainMenu()
     {
         GUI.DrawTexture(new Rect(Screen.width / 2 - 475,-25,380,380),WOZ);
 
         if(GUI.Button(new Rect(Screen.width / 2 - 55,220,110,45),"Play"))
         {
                 animation.Play("FTH");
 
                 show = "PlayHouse";
         }
