Xara Designer Pro 16 unable to use the contact page in template

[The Slug]

It is a XaraTemplates.com template and I have used his approach for email forms successfully with my provider.

Have you changed the Placeholder as per the above instructions on all Variants?
Can you upload your changed code here?
