Solution for "next" with single button

Hi,

I have 2 series of animation and i want them play one and one when i click left mouse button.

Here's sample of my code (because it to long:

 var P1 : GameObject;
 var P2 : GameObject;
 var P3 : GameObject;
 var P4 : GameObject;
 var P5 : GameObject;
 var click1 = false;
 var click2 = false;
 var click3 = false;
 var click4 = false;
 var click5 = false;
 
 function Start (){
 click1 = true;
 }
 function Update (){
 
 if (click1)
 {
     if (Input.GetMouseButtonDown(0));
     {
        P1.animation.Play("panel1");
     P2.animation.Play("panel2");
     P3.animation.Play("panel3");
     P4.animation.Play("panel4");
     P5.animation.Play("panel5");
     click1 = false;
     click2 = true;
     }
 }
 
 if (click2){
     if (Input.GetMouseButtonDown(0))
     {{
     if (click1)
     {
     P1.animation.Play("panel1E");
     P2.animation.Play("panel2E");
     P3.animation.Play("panel3E");
     P4.animation.Play("panel4E");
     P5.animation.Play("panel5E");
     }}}
 }}

I try that code but it does'nt make sense.

Any one show me some brighter ideas.

Thanks.
