The instructions are meant to get a search form onto the results page. This means that you should have already functioning search and results pages. Is this the case? If not you can create these pages with the DataAssist wizard.
Once you have the search and results pages created you can then edit the results page to include a search form. So that we don't get the process confused please make sure that you have the functioning search and results pages, then create a new thread and post specifics about how you would like it updated.
