Page header change to reflect group header on page

[strathbat]

I know there's a simple way to get the page header to chage to reflect the first group header on the page below it - but I've forgotten it.

Not sure I'm following but you put the group header field in the page header rather than the group header.

This could be misleading as some details may go with another group header but don't show that way because it's in the page header which changes only once per page.
