Thanks so much that appears to work! I think it was just missing a quote before "NEWcol"
Many thanks for your reply.

NAME
Class::MakeMethods::Utility::Inheritable - "Inheritable" data
SYNOPSIS
package MyClass;
sub new { ... }
package MySubclass;
@ISA = 'MyClass';
...
my $obj = MyClass->new(...);
my $subobj = MySubclass->new(...);
use Class::MakeMethods::Utility::Inheritable qw(get_vvalue set_vvalue );
my $dataset = {};
set_vvalue($dataset, 'MyClass', 'Foobar'); # Set value for class
get_vvalue($dataset, 'MyClass'); # Gets value "Foobar"
get_vvalue($dataset, $obj); # Objects "inherit"
set_vvalue($dataset, $obj, 'Foible'); # Until you override
get_vvalue($dataset, $obj); # Now finds "Foible"
get_vvalue($dataset, 'MySubclass'); # Subclass "inherits"
get_vvalue($dataset, $subobj); # As do its objects
set_vvalue($dataset, 'MySubclass', 'Foozle'); # Until we override it
get_vvalue($dataset, 'MySubclass'); # Now finds "Foozle"
get_vvalue($dataset, $subobj); # Change cascades down
set_vvalue($dataset, $subobj, 'Foolish'); # Until we override again
get_vvalue($dataset, 'MyClass'); # Superclass is unchanged
DESCRIPTION
This module provides several functions which allow you to store values in a hash corresponding to both objects and classes, and to retrieve
those values by searching a object's inheritance tree until it finds a matching entry.
This functionality is used by Class::MakeMethods::Standard::Inheritable and Class::MakeMethods::Composite::Inheritable to construct methods
that can both store class data and be overriden on a per-object level.
REFERENCE
find_vself
$vself = find_vself( $dataset, $instance );
Searches $instance's inheritance tree until it finds a matching entry in the dataset, and returns either the instance, the class that
matched, or undef.
get_vvalue
$value = get_vvalue( $dataset, $instance );
Searches $instance's inheritance tree until it finds a matching entry in the dataset, and returns that value
set_vvalue
$value = set_vvalue( $dataset, $instance, $value );
Searches $instance's inheritance tree until it finds a matching entry in the dataset, and returns that value
