simplest way that comes to mind is to used a shared variable and some formulae.
1 formula in the group header, set the shared variable to true.
1 formula in page footer to suppress the section if the variable is false
1 formula in the page header to set the variable to false
each page sets the formula to false, the group header can override it.
that would be the first attempt...may have to fine tune where the resetting formula is.
Hope this helps
