I have a contact form on my Contact Us page as follows;

    {{block type='core/template' name='contactForm' template='contacts/form.phtml'}}

The form displays correctly but when I click 'Submit' the page simply refreshes, clears the form, and no confirmation/failed message displays.  I also don't receive any email.

In my System > Configuration > Contacts I have '*Enable Contact Us*' set to 'Enabled' and a correct email address in '*Send Emails To*'.

For the record, I'm using Magento 1.9.1

If anyone can offer some assistance that would be great.

Many thanks
