I am trying to make a “previous” button as it follows; There are 5 movie clips in the scene and one button, everything placed in one frame. I gave those movie clips **\_alpha=0** ; on the stage. I wrote the following code on the button

on (press) {  
if (\_root.two\_mc.\_alpha=100)  
{  
\_root.one\_mc.\_alpha=100;  
\_root.two\_mc.\_alpha=0;  
\_root.three\_mc.\_alpha=0;  
\_root.four\_mc.\_alpha=0;  
\_root.five\_mc.\_alpha=0;  
}  
if (\_root.three\_mc.\_alpha=100)  
{  
\_root.one\_mc.\_alpha=0;  
\_root.two\_mc.\_alpha=100;  
\_root.three\_mc.\_alpha=0;  
\_root.four\_mc.\_alpha=0;  
\_root.five\_mc.\_alpha=0;  
}  
if (\_root.four\_mc.\_alpha=100)  
{  
\_root.one\_mc.\_alpha=0;  
\_root.two\_mc.\_alpha=0;  
\_root.three\_mc.\_alpha=100;  
\_root.four\_mc.\_alpha=0;  
\_root.five\_mc.\_alpha=0;  
}  
if (\_root.five\_mc.\_alpha=100)  
{  
\_root.one\_mc.\_alpha=0;  
\_root.two\_mc.\_alpha=0;  
\_root.three\_mc.\_alpha=0;  
\_root.four\_mc.\_alpha=100;  
\_root.five\_mc.\_alpha=0;  
}  
}

but it doesn’t work! What do I have to do to make it right?
