Crystal Reports no summary is allowed for formula - crystal-reports

Question

I have seen several examples that say you can create a running total, but that doesn't work for me either. Here is my data from Oracle:
Select 19000 as sales, 'Ted' as teammember from dual
union select 150000, 'Bob' from dual
union select 80000, 'Sally' from dual
union select 8000, 'Sally' from dual
My formula for commission:
If sum({Command.SALES}, {Command.TEAMMEMBER}) *.2 < 20000
then sum({Command.SALES}, {Command.TEAMMEMBER}) *.2
else 20000
My formula for sumval:
whileprintingrecords;
global numbervar sumval;
sumval :=sumval + {#Commission};
I put teammember and sales in the Detail section. I put Commission and sumval in the Group Footer. I want total sales and total commission in the report footer.
It won't let me create a summary, so I put commission and sumval in total. The value 41,400 would be correct. The existence of Commission in the Footer does not affect the value of sumval.
My report is like this:
Bob 150,000 20,000 20,000
Sally 8,000
sally 80,000
88,000 17,600 37,600
ted 19,000 3,800 41,400
total 257,000 3,800 45,200

Answer 1

You can create another new formula, let's call it SumvalTotal, and do this:
whileprintingrecords;
global numbervar sumval;
sumval;
And place this in your report footer. You can use this for both your Comission and Sumval columns, since they should be the same.
That should get you:
Bob 150,000 20,000 20,000
Sally 8,000
sally 80,000
88,000 17,600 37,600
ted 19,000 3,800 41,400
total 257,000 41,400 41,400
