Joomla! Forum - community, help and support

Here's the situation:

Have Contacts restricted to registered only. On one page, I have a link to a contact in the Contacts.
If I'm logged in and click it, it shows up nicely. If I'm NOT logged in, I get the entire page with navbars, etc, but otherwise just empty.
How can I add some kind of error message like "You need to be a registered member and logged in to view this page"?

Solved: I didn't have <jdoc:include type="message" /> in the template's index......
