You got warnings on? It tells you about problems like this...

-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----
wesley at delltop:~$ cat ./test.pl
#!/usr/bin/perl -w

my @action;
my $cntr = 1;
$action[1] = 72;
my $tmp = 20;

sub do_action {
    my $arg = shift;
    print "Wesley says arg is $arg.\n";;
}

&do_action($action[$cntr]), " - To hdr matches $tmp";
wesley at delltop:~$ ./test.pl
Useless use of string in void context at ./test.pl line 13.
Wesley says arg is 72.
wesley at delltop:~$ 
-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----

And what's with the ampersand anyway? :-)

ATB,
Wesley.
