Crystal reports formating total fields

Crystal reports 11.00

I have written a report that has a number of sub-reports that print totals. The problem we are having is as follows :-

If there are no records in the sub-report we would like the total fields to print '0' at present they are returning a 'blank' where there are no records selected. Any ideas?

Where are you printing the totals?
  In the subreport or the main report?

How are you calculating the totals?

Sounds like your producing the totals in the main report using a Shared variable. When declaring the shared variable in the main report you could always declare it as 0 + itself.

e.g.
(In Subreport)
Shared NumberVar SubreportTotal
SubreportTotal:=Sum({Table.field})

(In Main Report in section after subreport)
Shared NumberVar SubreportTotal
SubreportTotal:=0+SubreportTotal;

In theory then if the subreport is blankl then subreportotal in the main report will still =0;

The other alternative would be to use a statement "if isnull subreportotal then 0 else subreportotal"

Please ignore syntax in the above.

I hope this helps, I haven't tested it myself so not to sure
