Conversion Application Ideas

Greetings!

I want to create an application in Flash that converts a blood alcohol reported in mg/l to mg/dl.

Attached, you will find a .fla file in it's current state. You will notice that I have a combobox included. I would like the user to be able to select the state of interest, which would subsequently display the legal alcohol limit for that state in a dynamic text field.

I would appreciate some advice which would guide me in the best route to get this thing working.

Thanks for any help and/or advice that you can provide!
