Steve,
I'm not sure what doc in the mailing list archive you mention, but I did
find this at http://groups.yahoo.com/group/libwww-perl/message/6616:
"There is a unchecked variable in HTML::Form that causes -w to complain if
you try to "uncheck" a checkbox... (ie: when you list the values of a
form, it has "on" and "undef" as the possible options for a checkbox, if
you try to set it to "undef" to uncheck it, it works ok, but -w complains
about use of undefined value in Form.pm)"
Does this sound like the error you're getting?
