Check webpage for containing specific text

Hi all!

I have a small experience working with scrips.

Need help getting this to work:

function Test()
{

var url = "https://www.consolidatedcredit.org";
Browsers.Item(btIExplorer).Run(url);
var browser = Sys.Browser("*");

var body = browser.Page("*").contentDocument.body;
var str = "debt";


// Checks the result
if (obj.Exists)
Log.Message("Object containing text '" + str + "' is found", obj.FullName);
else
Log.Warning("Object containing text '" + str + "' was not found.");


}

What I try to achieve: to search the site (consolidatedcredit.org) for any text that includes a letter "debt".

Can you guys help me with what I am missing? The current test does not even open up the URL specified. 

Thanks,

Roman
