Hi - thanks for the reply. The script is stripped bare - there is error
checking on the actual script and all queries work fine.
When I say it doesn't work - I just mean the user clicks on the link
and is returned almost immediately to the page as if nothing has
happened.
I have just tried it in Internet Explorer and it seems to work there -
but sometimes I have to "refresh" the page to see the effect, sometimes
it updates ok.
In firefox, sometimes it works and sometimes it doesn't. When it does,
the page updates itself to reflect the "move up" - if it doesn't work
refreshing has no effect.
If I try the link in firefox and it doesn't work and then close firefox
down and visit the same link on the same page and then try, it works
(hence a suspicion of caching or session issues).
As I say - it works perfectly in all browsers on my dedicated server.
Exactly the same script - just a different server - so I am assuming it
is a server issue.
I'm flummoxed!
Best,
Steve
