how do you want to determine which users data to display?
is this a users search? or is this a users profile page that will display the logged in users information?
the basic idea is to set the recordset to filter based on a variable, could be a session in the case of a profile page or a form variable in the case of a search page.
either way, you will need to know the name of the variable to filter on, then set the filtering in the recordset to use that variable
in the Results page documentation i pointed you to:
see the section titled "Create the recordset filter"
