First of all, add "use strict;" and "use warnings;". That would have caught
your problem:

You're declaring $string (as "my $string = ") inside a conditional clause, so
it will become invalidated outside that block. You need to declare it outside
the block:
[code] # Untested.
my $string;
if ($response->is_success) {
$string = $response->content;
}
[/code]
For more information see:

Next time, please use strict and warnings and you can use the perl debugger to
see for yourself where things go wrong:
