Hi,

I changed Contact_Name, Contact_Email to Not Null->Yes (so user is required to input something).

If I left those fields blank on the add form the error message (Column Contact_Name cannot be left blank) will not be generated, it will allow empty fields.
But those fields are visible when I validate links (default user name/email).

This is not the case when I input new links through admin, also modify form is behaving correctly.

Thanks
