Thanks for the great replies. It's working well now. Is it possible though to send an extra scalar as parameter to the subroutine? I have not been able to get this working. 
sub module_subroutine {
my (%hash,$scalar) = @_;
   return "The color of the ".$scalar." is ".$hash{color};
}
my %hash_to_send;
my $scalar = "water";
$hash_to_send{color} = "red";
print module_subroutine(%hash_to_send,$scalar);

I am using strict now as suggested and it tells me there is an odd number of elements in the hash assignment at my (%hash,$scalar) = @_;. What is going on here?
