Choosing random MC's from a specified set

Hi all,

I am attempting to create a gift finder that chooses a gift (a movieclip) based on the user's input. I have 3 drop down menus (gender, age, & persona) for the user to choose from. For each possible input (i.e. 21-30, male, gadget-guru) i will have 3 products that match and display one at random.

The way I was going about it became very complicated and heavy because I was basically thinking of creating a frame for each instance. Any direction would be greatly appreciated.

thanks!

I just wanted to add some pseudo code to help better understand my intention:

if txt fields == ("21-30", "male", "gadget-guru") then on release of "find gift" button display 1 of these 3 choices.
