Thanks Brenden, I've added a field for the UserID (called it EmployerUserID) and put the macro in. When saving the changes to the field, Kentico automatically changes the closing '%}' to '#%}', and then when I save the form, it inserts this into the custom table record: {% CurrentUser.UserID |(user)zbynekh|(hash)75d61197de44b7635caca22f9cc087ab40c04716e05bf2e230303ca44ea16bcb%}
Am I missing something about adding macros?
