Inserting Input data into a HTTP post.(revised)

[clasikcars]

I have been asked to add postal rates to a web page shopping cart checkout
procedure. After contacting the post office I discovered that they used XML
to receive postal rate requests and send back the rate for a certain size,
"from:" address, "To:" address and delivery service speed. The examples
they showed used a HTML "Text Area" and a HTTP post statement to send the
request however I need to use input from an input box and then insert this
information into the HTTP post. I have tried using variables but they are
sent literally rather than being substituted with the information from the
input statements. Is there a way to include the variable information as
part of the post? I am new to XML and would have thought that variable
substitution should be easy however I had no luck.

document.MyForm.action = "

document.MyForm.submit();
