Hello,

On a rollover, I would like one of my movie clips to dissapear. On a rollout, I would like it to reappear. (I have some large drop down menus on a site, and it becomes too confusing with the content. I want the content to disappear when the menu is scrolled down.) this is the code I have used, but does not work:

on (rollover) {  
content.\_alpha = 0;  
}  
on (rollout) {  
content.\_alpha = 100;  
}

(the movie clip that I would like to dissapear/reappear’s name is “content”)

Thank you for your help,.
