Pull Variables From URL And Post In Document Code?

my url read index.html?pagego=collections

here it he code I have that is pulling the variables from the URL

function getUrlVars(){
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');

[Code]....

and here is the code I use to alert

var hash = getUrlVars();
alert(hash['pagego']);

this works perfectly and alerts with the variable when I load he page.

Now when i am embedding my flash file i want to pass the variable to my flash by just adding the variable value to my embed code.

how can I do this?

here is my swf embed code

var so = new SWFObject("main2.swf?pagego="+THIS IS WHERE I WANT THE VARIABLE TO BE, "Preview", "100%", "100%", "9", "#ffffff", true);
so.addParam("scale", "noscale");
so.addParam("salign", "lt");
so.write("flashcontent");
