Crystal Reports Displaying at the group header

Message

     Hi,i have calculated sum of amount and it is being diaplyed in the group footer,and now i want the value of groupFooter to be in GroupHeade
ex:
GH------------------Total Value(60)-----I want the total to be displayed this way.
Name                                      Amount
A                                             10
B                                             20
C                                             30
GF(Group Footer)-----------------------(60)---(This is what  i am displaying currently)

i am calculating this value by using formula fields
i have taken Three fields.
 Reset and Display
in the Reset field declaring shared numbervar a;a:=0;
in the Display field declaring shared numbervar a;a:=a+{tbl.fieldAmount};

Display field is placed on Details tab and Reset field is Placed on GroupHeader by appling my condition when it is to be set as a 0.

 i have taken another FormulaField Result and in that i am calling the Display field, and it was displayed on the Group Footer

Now the Value in the Result Field must be displayed in the GroupHeader.

thanks in advance
