Hej Anonymous monk and thank for your reply,

I have to say that I've tried your other option with redirect some days ago, but it didn't work as I send header earlier then check is done and it seems not to like it.

But I think your first option is simply ingenious !! and I'll try that first thing in the morning. I didn't have a clue that action can be other then perl/cgi (couldn't find it anywhere in books I've read and was too afraid to try it).

Now when it comes to JavaScript, I really would be very happy if I wouldn't need to learn it just to be able to do some actions here and there sporadically. I just don't have time for that.

Anyhow, thanks a million for your time and help and perhaps you might wanna take a look at node How to uncheck one checkbox if some other is checked if you have some time over ?

P.S. And just for a record - I'm not a web developer, I'm just trying to help some of my colleagues to collect some data and that's all... :-)
