Not sure if I can give a good answer, but try doing a var_dump on
$_SESSION["Search Result"] and see what you get. I suspect that it is
null. If that's the case then track down where it is getting assigned.
It should look something like $_SESSION["SearchResult"] = $users.

The user will then click on the search result for which they want to view the details, and the information from that row will be populated inside the main page (the one that houses the iframe).
