Adding timed Re-Direct

[bradsickskater]

I would like to add a timed re-direct to a page which has a form. When the form is filled in, assuming it is successful, due to the code below they are given the following message :

[strong]define('TEXT_SUCCESS', 'Your diet request has been successfully sent to the team. Your details will be assessed by one of our resident experts and a your diet sent in response as soon as possible. Thank you.');
[/strong]

What i would like is for the above message to be displayed for around 5-6 seconds, then the user re-directed to a new page. How can i do this ?

Below is the full code of the page.

Thanks

best bet would be a META REFRESH
