[Help for a script]

Hello guys!

I'm trying to write a script but it seems I'm way way too rusty and cannot even remember the basics right now and I would like to ask help to someone more experienced than me.

What I'm trying to do (with no success) is a scritp that makes an object clickable and that, once clicked, gives you a menu with 3 choices, randomly picked from a list (I was trying to link a notecard with the list of options to it) and state the one you picked in local chat.

Any clue about how I could do that? :D

thanks!
