joomla contact form doesn't give confirmation

i'm using Joomla! 1.5.15 (with a custom template) and I've created a contact form.

Unfortunately I can't get it to work; when I fill the form in and click "SEND", nothing happens - the form just gets reloaded (empty) with neither success nor error message.

What can I do to i开发者_开发知识库mprove on this?

thanks Patrick

Check to see if the problem remains using one of the default joomla templates. It could be something as simle as you not including the "message" block in your own template
