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".
