Supress Page Header on Subreport in Group Footer but Not Multiple Report Main Pages

Using Crystal Reports ver 2106 sp 6
Report Header is suppressed.
There is a main report and one subreport in the Group Footer.

The report is used to print multiples of invoices with a Summary page.
The summary page prints after each printed invoice.
The Summary page holds specific information and different page orientation.

I need the Page Header to print on all pages of invoices but not when the Group Footer with the Subreport Summary page prints.
I have entered the code below.
This works to stop the Page Header listing on the Subreport Summary page and this is good.

Problem -The Page Header from the Main report prints only on the first invoice not the subsequent invoice pages.


In the report header add a formula
 WhilePrintingRecords;
 Global BooleanVar SuppressPageHeader := False;
 ""

 In the group header add a formula
 WhilePrintingRecords;
 Global BooleanVar SuppressPageHeader;
 SuppressPageHeader := False;
 ""

 In the group footer add a formula
 WhilePrintingRecords;
 Global BooleanVar SuppressPageHeader;
 SuppressPageHeader := True;
 ""

 Right click the page header in the left margin
 Click SECTION EXPERT
 Click the FORMULA BUTTON to the right of SUPPRESS
 WhilePrintingRecords;
 Global BooleanVar SuppressPageHeader;
 SuppressPageHeader
