I need a developer familiar with using Flex's external interface with JavaScript. I have an existing Flex application on the following page: 

http://www.decalstore.com/Create-Your-Own-Custom-Text-Decals-P299.aspx

Below this Flex application are duplicate HTML controls for my shopping cart. When the HTML controls are updated the price updates accordingly. Currently my customers have to enter their information twice before they can add the product to their cart: once in the Flex application and then again in the HTML controls. What I need is for the Flex application to interface with JavaScript code that will then update the HTML controls in realtime as changes are made in the Flex application.

I will provide the source files for the Flex application. You will need to create the JavaScript code that updates the HTML controls and will need to interface the Flex application with that JavaScript.

If you're up to the task please contact me with a quote and estimated timeframe for completion.
