I'm trying to accomplish the same as what is done on this site:
http//libkod.info/officexml-CHP-9-SECT-5.shtml#officexml-CHP-9-FIG-16

The only difference is I have more than one parameter to pass in the URL.

So where 
query = "http//webservicex.net/uszip.asmx/GetInfoByZIP?USZip=" + zip
is being passed to send I need to do something liek this but can't figure out the syntax 

query = "http//webservicex.net/uszip.asmx/GetInfoByZIP?USZip=" + zip & USCity=" + city & USState=" + state
How would I go about doing this?
