Animation Playback

Hallo everyone,

Lately i have encountered a confusing problem while trying to create a book with scrolling pages. I have a book object and i want the turn animations to play each time I press the appropriate button. I have one button for Next page and one fore the previous page. All works fine until I press the "Previous button" .After i pressed the "Previous" button once the animations for "Next" button stop working, while the "Previous" button animations still work correctly.

Code:

     if(buttonPressed)
     {
         if (GUI.Button(Rect(600,-40,200,100),"Previous Page",buttonStyle))
         {    
             if(pageCount > 1)
                 {
                     var pageIndex = pageCount-2;
                     pageArray[pageIndex].animation["turn"].speed = -1;
                     pageArray[pageIndex].animation["turn"].time = pageArray[0].animation["turn"].length;
                     pageArray[pageIndex].animation.Play("turn");
 
                     pageCount--;
                 }
           }
      }

 if (GUI.Button(Rect(1200,-40,200,100),"Next Page",buttonStyle))
         {
             
             if(pageCount > 0)
                 {    
                     var pageIndex_2 = pageCount-1;
                      //pageArray[pageIndex_2].animation["turn"].time = 0;
                     pageArray[pageIndex_2].animation.Play("turn");
 
                     pageCount++;
                 }    
 }

I suspect the problem lying into this line:

                     pageArray[pageIndex].animation["turn"].time = pageArray[0].animation["turn"].length;

But i tried several things with no luck. So are my expectations true? And how could i solve this problem?

Thanks in advance.
