Smart Pricelist with GUI

Okay I need a help from you guys here about:

  • How to do a smart pricelist in Macromedia Flash

Okay, let me tell you… how I want the ‘smart pricelist to behave’

  • There are a few items in the blue box (list of the items along with their prices). So, once I double-click/Drag it to the Pink box,
  • It will automatically gives the total of the item.
  • And the item also can be removed from the Pink box by double-clicking/dragging the deserved item in the Pink box.

Please help me how to do this.
