Start with the first error message:

Then look at line 2:

This indicates that $_POST['searchterm'] is undefined. Why isn't it defined?
In order to show up in the $_POST array, it would have to be POSTED, ie you
could put it into a hidden field that could show up after the user pressed a
Submit button.
However, it doesn't appear that you are doing that. (Either that, or I snipped
too much off your original post!) You have Previous and Next hyperlinks, each
of which passes the page number in the query string. Perhaps you could also
pass the searchterm(s) in the query string. Or, you could store them in the
$_SESSION array. If you do this, be sure to start the session.
