If anyone can help me out, or at least point me to a resource which might help, I would be grateful. Thanks.
function didYouCheckIt()
{
if (!document.getElementById('myCheckBox').checked) {
alert('You must check the box.')
return false
}
return true
}
}
click a checkbox and click a button to continue to the destination.
Also, no reason to return true. Return false stops the form from performing it's normal function onSubmit, so you want to let the Javascript manage the submit:

if (! document.getElementById('myCheckBox').checked) {
alert('You must check the box.')
}
else { form.submit(); }
return false;
}

<form method="get" action="http://www.example.com" onSubmit="return didYouCheckIt();">

Rocknbil, Your script looks like it is going to set me on the proper path. I think I can figure out how to set the session cookie (we'll see).
<form method="get" action="http://www.example.com" onSubmit="return didYouCheckIt();">
how can I pass the url passthrough.html on the referring page, for example,
<a href="validate.html?passthrough.html">go here</a>
to the action attribute in the form?
A discussion of this approach is here [webmasterworld.com] including a complete sample script to do the job.
Basically all you'd do is put this Javascript on the "exit page." Come to think of it, if you redirect them to the "exit page", in effect you probably wouldn't need the check box.
Why not go for a more modern server side language, like PHP or ASP.NET?
Well, no good reason, I guess except, as a cut and paster, I've had some experience working with Perl scripts, plus the script Rocknbil referred me to is a Perl script. I just don't know enough to write code from scratch (I was a communications major 30 years ago - no programming ability at all! ;)
