Q: I tried the date form sample on your site and it doesn't work.
A: Forms containing scripts must be published. This prevents someone from sending you a form containing virus-like scripts. The scripts won't work unless you publish the form. You won't be warned that it needs to be published, so if a form (or template) doesn't work as expected, try publishing it.
Q: Where is the best place to publish forms?
A: If you use Exchange server, publishing them to the Organizational forms
library lets everyone use the form. But if the form is only for your use, it's
usually much easier to access if you publish it to an Outlook folder. When the
folder is selected, the custom form is listed at the bottom of the Actions menu,
so it's easy to use.
