Basic Script Help - Probably easy but i'm clueless

[adamci]

Hi, I have a shipping script that I'm trying to modify to my needs. Basically the script has you select your state or country from a drop down menu then takes the price attached to that state (zone) and fowards it to your shopping cart. What I want the script to do is take a ZIP CODE that the user inputs into a text box and search for the proper zone in the script to pass the price. I don't think anyone would want to scroll through hundreds of zip codes and select it! So if there is a way to modify this script to do that please let me know! THANKS!

 

Here is the script:
