Suppress a field in the page footer unless it's the last page of the group

Question

Hi,
I have a report set up where one can pull invoice information.  There is a page footer used for every page which contains a field that I only want visible when it is the last page of the group.
For example, one might pull several invoices, each invoice being its own group.  A field would be suppressed in the footer unless it is the last page of that particular invoice.
Is this something that can be done in Crystal Reports XI?
Thank you.

Hi,
Alright, it's a bit rusty but here's how you can do it:
1) Create this formula and place it in the Report Header:
whileprintingrecords;
numbervar n1 := groupnumber;
2) Create this formula and place it in the Group Footer:
whileprintingrecords;
numbervar n := groupnumber;
3) Create this formula and place it on the Page Footer:
whileprintingrecords;
numbervar n;
4) Right-click the above formula (Formula on the Page Footer) and select Format Field > Common tab > click the formula button beside 'Suppress' and use this formula:
numbervar n1;
numbervar x;
if currentfieldvalue <> n1 then
  x := 1;
  true;
else
  x := 0;
  true;
5) Right-click the field that you wish to always suppress except on the last page and select Format Field > Common tab > click the formula button beside 'Suppress' and use this formula:
numbervar x;
if x = 1 then true;
Let me know how this goes!
