Repeating subforms within a subform

Hi

I am producing a form which I want to have repeating reports.  I have created a subform for the report which also contains a section (further subform) which can repeated in the report by clicking a button.  This works fine

When I come to repeat the original report I cannot get the section to repeat itself in the new report, it just repeats in the original report. 

Any ideas?

Many thanks
