$Attachment.Created will work, too.
To display the Date, I had to add it in. For Created, do you need to have the extra date field or will it be automatically displayed if you have the $Attachment.Created variable for display?
For every resource I add, there appears to be a blank line above the record display on the front end page.
Any idea why?
Update: I had the Layout div repeated inside another Layout div. All sorted.
Sweet. That is exactly what I needed. Can the displayed date be formatted?
No, the Created property is built into every object.
<% control Attachement %>$Created.Nice<% end_control %>
<% control Attachement %>$Created.Format(m-d-y)<% end_control %>
More in the SS docs on date formatting.
Brilliant. This is cool. Thanks UncleCheese.
