Newbie retrieving Lead record using name passed in URL

I am a newbie so any advice is most welcome as my whole approach may be wrong.  For a new web guest where I don't yet want to require the guest to reveal name and contact information, I have a page that creates a unique ID, saves this as a cookie, and uses web-to-lead to create a new Lead record with this name and his interests from a form multi-select list.  This all seems to work.  When this lead comes back in a new session, this page sees that he has a unique ID in cookie and assigns a new visualforce page with a URL parameter containing the existing unique ID.  The new page attempts to look up his Lead record interests using a controller extension with a select statement.  I have looked through many examples online of how to code the controller (some of which gave me syntax errors) and picked what seems like the simplest example for a template that "compiles".  From the start, the controller query is returning nothing.  So I have simplified the controller query to only try to find the first lead record to return and this also returns nothing.  My controller extension code is:

public class LeadNameLookupTest 
    public LeadNameLookupTest(ApexPages.StandardController controller) {}
    private Lead guest;
    public LeadNameLookupTest()
         guest = [select ID, name from Lead limit 1];
    public Lead getLeadRecord()
        return guest;

The visualforce page below third alert does display the unqiue ID being passed via URL but the earlier alerts display nothing in alert popup.  The  page code is:

<apex:page standardController="Lead" extensions="LeadNameLookupTest">
var guest_name = "{!$CurrentPage.parameters.guest}";

Maybe the controller example I used is flawed.  I did see other more complicated templates. I even tried some of these more complicated examples but they would not "compile" or the page script reference to controller result failed.  Or maybe my alerts are a problem.

Hi Alan,

Can you please share with me your complete issues & your requirement.

Not sure what info you need.  To summarize my earlier long description, I am unsuccessful in creating a Lead controller extension that will retrieve a record using Lead name and display fields from the retrieved record in a visualforce page. Even when select statement only selects first Lead on file, the visualforce page display shows populated Lead fields as empty.

Incidentally, I also tried using a form and input field to display the LeadRecord fields and it also displays fields as empty.

Hmmm.  I commented out second line of controller extension code and referenced this as a custom controller in page.  Alerts stopped working but form input now displays the retrieved record fields.  So, I need to know how to convert this custom controller into a controller extension so I can also use the standard controller methods (rather than create references to all the standard controller methods in the custom controller).
