simple Calculator in Flash

I need a very simple Productcalculator I already prepared in Excel. I need the fla-file to change values and design later on. It can be done with as2 or as3. Detailed description of the form: <Please download the Excelfile> The green fields should be invisible for the user as this is unnecessary information. The green field of "special functions" show prices per unit. These shall be visible for the user but only be editable through me in the fla-file. There are fields where the client can choose between 3 items but only one of these options is possible. Right now I have there a 1 for the item and the others must be 0. There I want to have a radio-button. If I check one, the others two must uncheck automatically and so on. The same with the "Player" the the user shall choose: Standard or Extended VErsion and her is also only one option via radio button possible. Thats all. I will send a very simple design later.
