Use of uninitialized value in hash element at C:/Perl/lib/LWP/Protocol.pm line
55 (#1)
(W uninitialized) An undefined value was used as if it were already
defined. It was interpreted as a "" or a 0, but maybe it was a mistake.
To suppress this warning assign a defined value to your variables.

To help you figure out what was undefined, perl tells you what operation
you used the undefined value in. Note, however, that perl optimizes your
program and the operation displayed in the warning may not necessarily
appear literally in your program. For example, "that $foo" is
usually optimized into "that " . $foo, and the warning will refer to
the concatenation (.) operator, even though there is no . in your
program.

Can't call method "find_input" on an undefined value at
C:/Perl/site/lib/WWW/Mechanize.pm line 1586 (#2)
(F) You used the syntax of a method call, but the slot filled by the
object reference or package name contains an undefined value. Something
like this will reproduce the error:

$BADREF = undef;
process $BADREF 1,2,3;
$BADREF->process(1,2,3);

Uncaught exception from user code:
Can't call method "find_input" on an undefined value at C:/Perl/site/lib
