I had to run phpsurveyor outside moodle and link to it in the bottom frame (click "add resource" in the drop-down box and add a webpage link), that is why the phpESP "questionnaire module" adaptation may be a better option, even though I prefer the former a little (very active developer and more functions). The questionnaire module is an add-in that is not even on the modules download page. Get the latest version from CVS at http://cvs.sourceforge.net/viewcvs.py/moodle/contrib/questionnaire/ or download version 4 from the thread at http://moodle.org/mod/forum/discuss.php?d=5639 (though this may not be the latest version).
Note that these options are for collecting information only, and don't allow much immediate feedback to users. If that is required the quiz or survey modules are better options.
PS I sent you an email earlier today.
