I was wondering if there may be something missing in this thread.
I tried the above code and what happens is that only the 1st category is submitted and the rest are deleted.
I tried the PugDog suggestion and it works but in the admin screen it shows the link with no categories.
I tried combining the 2 suggestions and ended up with the link in no categories and it does not appear asa an orphan.
Any clarification would be appreciated.
Thanks,
Richard White
