I'm using this code to get a url using LWP::Simple

one of the arguments I use is being input from command line when the perl script is starting. Since I'm using this script as a helper for a larger c++ app, there isn't much code: 
#!/usr/bin/perl -w

use LWP::Simple;
use strict;

my $word=$_;

my $url="http://dictionary.reference.com/search?q=$word";
my $html=get $url;
open(HTMLTRANS,">./htmlTransfer.lib");
print HTMLTRANS "$html";
close(HTMLTRANS);

[download]
thats all

when I run the script like this: perl getURL.pl test

I get the error uninitialized value in concatenation

I know the url I'm creating is correct, and I can't figure out where th error is coming from

any help?

Updated Steve_p - added code tags
