Hi every one,

I read a lot of threads in this forum and got a lot of help, thank you.

**Here is my question**

When a movie clip is clicked on, another movie clip will fade out.

The problem is that the clip that needs to fade out just disapears in a second,  
is there a way to controll the speed.

I read a lot of info about this for complicated setups, is there a simple fix for this.  
I was hoping I could just do this designR\_mc.\_alpha = 0/4;  
But that does not work.

HERE IS THE CODE

design\_mc.onRelease = function()  
{ designR\_mc.\_alpha =0;

}

Thanks to every one
