#40865 — I cant understand this error when i click a link on my website

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

 /home/nikos/public_html/cgi-bin/metrites.py in ()
   12 
   13 htmlpage = form.getvalue('htmlpage')
   14 if re.search( r'(.html|.py)', htmlpage ):
   15         htmlpage = htmlpage.replace( '/home/nikos/public_html/', '' )
   16 else:
re = <module 're' from '/usr/lib64/python2.6/re.pyc'>, re.search = <function search>, htmlpage = ['/home/nikos/public_html/index.html', 'pelatologio.py']
 /usr/lib64/python2.6/re.py in search(pattern='(.html|.py)', string=['/home/nikos/public_html/index.html', 'pelatologio.py'], flags=0)
  140     """Scan through string looking for a match to the pattern, returning
  141     a match object, or None if no match was found."""
  142     return _compile(pattern, flags).search(string)
  143 
  144 def sub(pattern, repl, string, count=0):
global _compile = <function _compile>, pattern = '(.html|.py)', flags = 0, ).search undefined, string = ['/home/nikos/public_html/index.html', 'pelatologio.py']
<type 'exceptions.TypeError'>: expected string or buffer 
      args = ('expected string or buffer',) 
      message = 'expected string or buffer'
==============================

The regular expression functions expect a string (or a buffer), but
you're passing it a list.

Learning to read exception tracebacks is one of the important parts of
becoming a competent programmer.

But with different arguments. It's http://superhost.gr/?htmlpage=files.py
http://superhost.gr/ and the arguments to your regex are coming up as
"string=['/home/nikos/public_html/index.html', 'files.py']" which is
clearly a list of strings.
In the case of http://superhost.gr/ it's probably just a single string

The documentation for getvalue says """If the submitted form data contains
more than one field with the same name, the object retrieved by 
form[key] is
not a FieldStorage or MiniFieldStorage instance but a list of such 
instances.
Similarly, in this situation, form.getvalue(key) would return a list of
strings."""

This suggests that the webpage may in fact have 2 fields with the name
"htmlpage".
