With only modifying the @Identifiers-line to
my @Identifiers = ('1', '2', '3', '4', '5');
and filling the table with the above mentioned data, the output
is as follows:

Value => 1, Identifier => 1,
Value => 23, Identifier => 2,
Value => 456, Identifier => 3,
Value => 78, Identifier => 4,
Value => 9, Identifier => 5,

Which looks just fine. Guess which value I then Null'ed? :-)

Value => 1, Identifier => 1,
Value => 23, Identifier => 2,
Value => 456, Identifier => 3,
Value => 456, Identifier => 4,
Value => 9, Identifier => 5,

Kind regards,
H. Buurman
