[AccessD] text box in page header

Access2003, WinXP

I have a text box in the page header of a report that changes values as the 
records move from one group to another.   This text box on the first page of 
"group 2" still has the value for "group 1".   Is there a way to get the 
correct value for a new group level in this text box, or do I have to move 
text box to the group header section?

Thanks
