As I said in the chatterbox, perhaps you mean add_format rather than addformat. The error thrown is pretty clear. If in doubt check the module documentation.

Update: OP changed:

my $format      = $WS->addformat();

[download]

to

my $format      = $WS->add_format();

[download]

Based on my reponse.
