Unfortunately, there is probably more than one possible reason for those controls not to be visible on this form (and it is a form, not a report).
One possibility is that there are no records in the form's recordsource, and that recordsource is a non-updateable query.
Also, in the design view screenshot, I do not see the subform. Is it in the Footer section, out sight in the screen shot? What are the Parent/Child Linking fields involved in it?
Thanks for providing additional information to help find suggestions.
