Oh, that's probably because "enquiry" is a local variable. You need to
call the #count _class method_ on your model. So you'll have to do it
like this:
Enquries Today: <%= Enquiry.count %>
Notice, I use a capital E. The #count method is not available on
instances of Enquiry (a specific record in your database), but as a
class method of your model. "Enquiry" in your case.
