Which version of Python?

Can you please paste those few lines of code (say, lines 163 to 170).

I can't see what the "mail = None, comment = None" is meant to be.

Is the same lines i posted in the 1st post

**************************************************************
	# insert guest comments into database if form was submitted
	if "@" in mail and comment not in ("Σχολιάστε ή ρωτήστε με
σχετικά....", ""):
		try:
			cursor.execute( '''INSERT INTO users(mail, comment) VALUES(%s,
%s)''', (mail, comment) )
		except MySQLdb.Error:
			print ( "Error %d: %s" % (e.args[0], e.args[1]) )
**************************************************************

Also both mail and comment variables are taken from input in form
fields.

mail = form.getvalue('mail')
comment = form.getvalue('comment')

If this is to reset the two variables after inserting into the
database, you may want to use either:

mail = None; comment = None  # semicolon not comma
or
mail = comment = None  # chaining assignment

Is that the line with the error, though?
