Re: Receiving email:
Please could you check that email being sent via the form isn't being put in a spam or junk mail folder by your email client? It's sometimes happens to mail sent direct from websites. If that is what's happening you will just need to mark it as not junk mail.
Do you have an alternative address that you could put in your WA_Globals.php file (i.e. Hotmail, Yahoo, Google Mail etc) just to test with?
I have sent an email via the form, let me know if you have received it. Please could you also let us know who your hosting provider is, it might help.
Re: Contact and thanks pages design:
The first step in creating a styled page for the contact form and thankyou pages is for you to find a page in your closest to looking like the contact/thankyou pages you want to create. It's best not to have the flv video on it as people will just be entering details and going immediately to the thank youpage and back to your main content.
When you've selected a page, save it as contact_thanks.php in the root folder of your site.
Edit it in Dreamweaver to remove any stuff you don't need on it, including any extraneous code in code view. You want to end up with the page with just the basic styling you need for your contact and thankyou pages, - the header, menu, footer and content areas.
When you have it as you want it, save it as a template: Dreamweaver Menu > File > Save as Template. In the 'Save as Template' window that opens, give it a description ( Contact and Thanks Pages) and save it as contact_thanks. When you are asked 'Update Links?" click 'Yes'.
You will now have this template in your Templates folder which is inside your root folder.
When you've done that, please could you create a new page from the template (File > New > 'Page from Template' (choose the template you've just created) and save that page as example.php, upload it to your server so I can see what we have?
