Do it like this:
my $From;
eval {
$From = $Document->GetFirstItem('From')->{Text};
};
if ($@) {
$From = ''; # or whatever default you want
}
The eval{} will make sure the error doesn't kill your script, the $@
contains the error message if there was an error. In such case you
can set the $From to whatever default you like.
You may even do this:
my $From = ''; # the default
eval {
$From = $Document->GetFirstItem('From')->{Text};
};
