Erm, sorry. I was not able to test with opera, and quite mainstream [it seemed to be] JS syntax, which should work in all browsers. Seems that it is not working though.

The script there has a with{} block, which enables us to have mor logical looking code. I guess Opera understands that with{} block, as it drops no error on that. It enters that block, and gives an error on a reference, which should be parsed in the context of the with{} block.

We have this script for quite some days now online, and you are the first to complain about a JS error. Can you please check with another Opear browser version too? I suppose this is a bug in Opera. Or in case you think we have buggy JS code, then I would be happy if you would be able to provide us a better one, so everyone will be satisfied.

Thanks for your report

Well, I've tested it with several versions, and it seems it only occurs with Opera 7 (Opera 6 doesn't complain about it).

Unfortunately I'm at work right now, so I don't have the time to present a better version - sorry (maybe when I'm at home).

Maybe no one noticed it so far, because JS-error notification is off as default (as far as I can remember).

That with{} construct was removed some time ago, so this should be fixed. Please reopen if you still experience the problem.
