Flash Select Menu?

k im looking for like a menu for my ugh “Flash based message center/console” here is a link to how i want the inbox page to be… (CLICK) of course my thing right now is just set to look selected, "it just changes frame of movie clip on click, anyways there are some buttons on the bottom, (some i still have to add) but

delete = faded if # of selected = 0
save = faded if # of selected = 0
reply = faded if # of selected = 0 or more than 1

also i need to make it so when a message or the movieclip that the message is in is double clicked it takes them to a frame where the message will be viewed…, so like i guess that would be some function like on.DoubleClick, idk…

so get it? yeah, basicly i need to know how to make a select menu

and if you haven’t notice it needs to be able to select multiple ugh messages.

any links to revelant tutorials or tips, where to start etc.

THANKS A LOT TO ANYONE WHO HELPS I HAVE ABSOULTELY NO IDEA WHERE TO START OR WHAT TO DO!
