    Hey, Terry.

    The {} is a way of creating a new Object (just like doing "var
something=new Object();"). Just to note: if you want to create an
Array, you can use "[]" as well as "new Array()" (like this: "var
myarray=[];").

    The "search" property of the "location" object (accessed through
"window.location.search") contains the "?" and everything after that
in a URL (or empty, in the case that the request doesn't contain any
parameter in the URL). By doing ".substring(1)", he is removing the
"?" from the string and getting only the wanted data. After that you
can just parse it as you prefer.

  Amplexos.
