Random layers

[FONT=Times New Roman][SIZE=3]Hi guys,[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3][/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]I’m new to the forum and very, very new to ActionScript.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3][/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]I have 10 different ‘banners’ on a layer called ‘bg’ they all fade in then out then the next ‘banner’ fades in then out and so on.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3] [/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]And 14 ‘other’ images on separate layers which fade in and then out.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3] [/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]What I would like is the ‘other’ images to randomly appear on the ‘banners’ layer[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3] [/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]So it looks a bit varied, e.g. ‘banner’ 4 would have ‘other’ image 12 on one loop but no the next one ‘banner’ 4 may have ‘other’ image 3.[/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3]Thanks for your help in advance.[/SIZE][/FONT]
