[Zope] perl scripts Global symbol ?

I think I have finally gotten perl script up and running ? Whats wrong with this code my @res; for ($self->{f1}->objectValues) { push(@res, join(": ", $_->id, $_)); } join("\n", @res, "done"); Error Type: PerlError Error Value: syntax error at test line 3, near "self my " Global symbol "@res" requires explicit package name at test line 3. Global symbol "@res" requires explicit package name at test line 6. Global symbol "@res" requires explicit package name at test line 8. I am obviously missing something, Chris
