in responce : but why it works for me, I don't know. Try it now

I think you are just the lucky guy :).
ok here is a hint upon following up the install script is not creating the Bad_link colum in the link table at all and that is why the script runs when you call it as a stand alone and not with an ID... I guess

hope that helps
