Crystal Reports Summary and Grand Total

Message

   Thanks that worked! show as percentage of grand total is the correct soulion. I have another problem. I have three levels of group. I want each grp to start in a new page. A group can span for more than a page. if the group end in a page the footer of the prv grp should also be in the same page
Plase refer this chart:
G1 Hdr
  G2a Hdr 
        G3a Hdr 
               G3a Dtls 
         G3a Ftr
<new Page>
       G3b Hdr
             G3b Dtls
       G3b Ftr
 <new page>        
        G3c Hdr
              G3c Dtls
         G3c Ftr
   G2a Ftr
<new page>        
   G2b Hdr 
       G3a Hdr
           G3a Dtls
      G3a Ftr
   G2b Ftr
G1 Ftr
<new page> 
So any grp should start in a new page . but if a prev level group ends the footer of the prev level group should reside in the same page and lower lever gorup
