No, it is that Crystal doesn't summarize where the results are variable...The way to summarize this may be a running total, that is DBlank's forte, but the way that I would do it is with shared variables.
for your case, probably 3 formulas will be needed, the hard one you already have.
In GH1 a reset formula:
shared numbervar total:=0;
"" //to hide the rest
In GF1, the display:
shared numbervar total
In the GH2, adding the sums together:
shared numbervar total;
local numbervar thisTotal := 0; //or whatever was displayed before
thisTotal := Sum (gross_ticket_extax, ticket_no)+Sum (total_tax,ticket_no);
total := total + thisTotal; //increment your sum
thisTotal //display the total for GH2
