Your problem description is still unclear. Perhaps you could step back 
and describe what you're actually trying to do, rather than trying to 
express things in terms of tables and arrays that are fairly meaningless.

For example:

"I have code to calculate shipping rates for usps. I also want to 
calculate shipping rates for fedex, ups and deutche post."

Firstly, think about how you want to get input and present calculation 
results. Build the html structure that you want to input data from and 
put the results into.

Secondly, get the base data needed for your calculations. I imagine this 
will be in the form of a table for each shipping method.

Thirdly, write functions for each shipping method that takes the input 
data (us zip code or country of destination, package weight, package 
dimensions) and then calculates and displays the shipping for that 
shipping method using the base data.

Perhaps I misunderstood what you're trying to do.

I suggest that you put all your code in a single script section in the 
head of the document, that you don't use the "language" attribute for the 
script section, but instead use the type attribute: type="text/javascript"

Ignore any elf-like apparition that tries to tell you this is wrong, and 
instead search the web to find out why this is right.

Later on you may wish to separate your js code and data, and possibly 
have some server side system that automatically generates new data files 
when you update some set of master shipping cost tables.

You have unescaped ampersands in your countries option list, and your 
innerhtml code includes html closing tags which it is usually a good idea 
to split up, eg instead of:

blah.innerHTML += "</B>";

use something like:

blah.innerHTML += "<"+"/"+"B>";

to avoid any sequence of '<' + '/' + letter occurring inside the script 
tags, as these may confuse the rendering engine.
