I am trying to construct a moose class that represents a single record retrieved from the db. I'm getting a problem which I'm pretty sure is from the attempt to assign values to a hash "property" of the class. But I could be wrong ;o) 

package AXRecord;

# Our libraries
use lib 'C:\Users\Jay\Desktop\SBS DEV\CODE\perl\Utilities';
use AXControl;
use AXSQL;


use Moose;
use DBI;

# Attributes
has 'Name' => (is => 'rw', isa => 'Str', required => 1);
has 'Fields' => (is => 'ro', isa => 'Hash');
has 'FieldCount' => (is => 'ro', isa => 'Num');
has 'Changed'  => (is=>'rw', isa => 'Boolean');
has 'Where' => (is => 'rw', isa => 'Str'); 
has 'ControlObject' => (is => 'rw', isa => 'Object', required => 1);
has 'Keys' => (is => 'rw', isa=>'Array');
# Contains a single record

sub BUILD
# Constructor
{
    my $self;    
    $self = shift;
    
    if (defined $self->Where)
        {
        $self->Select();
        }
}
# Insert the record
sub Insert
{

}
#Delete using the keys in the record
sub Delete 
{


}
#Update using the keys and values in the record
sub Update
{



}
#Save the record
sub Save
{


}

sub Select
{
    my ($SQLStr, $Cnt, $sql, @Values, $self, $Col, @Flds, $i);
    
    $self = shift;
    
    $SQLStr = "SELECT * FROM " . $self->Name . ' ' . $self->Where;
    $sql = AXSQL->new(ControlObject => $self->ControlObject, SQLString
+ => $SQLStr);
    
    #construct a hash using the metadata and the data from the actual 
+table
    $self->Fields = {};
    @Values = $sql->Fetch();
    #Get field Names
    $sql = AXSQL->new(ControlObject => $self->ControlObject, SQLString
+ => "show fields from '" . $self->Name . "'");
    @Flds = $sql->fetch();
    # Construct the hash
    for ($i..$#Flds)
        {
        $self->Fields{$Flds[$i]} = $Values[$i];
        }
    
    $self->Keys = ();
    $sql = AXSQL->new(ControlObject => $self->ControlObject, SQLString
+ => "SELECT column_name FROM information_schema.`key_column_usage` WH
+ERE table_name = '" . $self->name . "' order by ordinal_position");
    while (($Col) = $sql.fetch())
        {
        push $self->Keys, $Col;
        }
    
    $Cnt = $self->Fields;
    $self->FieldCount = $Cnt;
    $self->Changed = -1;

}

The error messages I am getting all seem to be caused by what I'm doing wrong in this statement 

$self->Fields{$Flds[$i]} = $Values[$i];

All of the declaration errors are about variables that work fine before that line. The hash Fields is a property of the class and I'm trying to populate it with fieldname/value pairs Here are the error messages (moose warnings excluded)
