Bounty for custom javascript code!

Seems this project is functional - yet I find no documentation.

I need some custom code done for a project i'm working on, and would appreciate some paid assistance.

This is what I need to accomplish:

I need to semi-automatically calculate a price of a product, while adding the product node, based on parameters specified in CCK fields calculated against a price list (which can be either a table in the database or many seperate nodes of the same content type - whatever makes this easier and faster).

I also need this price field to either auto-update on node view, or have the abbility to batch re-calculate the price for all nodes.

The calculation depends on 4 veriables, one of which should be looked up as "value is bigger then X and smaller then Y" (the other 3 must exactly match so there is no problem).

Eventually, after clicking the button, 3 fields would be filled in and the user will have the option to manually change any of them and/or perform further calculations.

If anyone has an idea and would like to help - please contact me using my contact page

Thanks!
