Thanks for your replies.
I prefer not to use the 'BACK' button and the scripts I write typically perform the validation within the script by using the script's URL in 'form action'. I'm using a pre-existing application and I'd like to revise it as little as possible.
What I'd like is for something like that used here on the Perlmonks site. For example, if you forget to fill in the title when creating a new node, the content in the text box is preserved when the 'BACK' button is clicked. How is this done?
Thanks.
