printing null values instead of zeroes

[gvg356]

I have a report output like
days Jan Feb Mar.....
1 3 2
2 2
3
....
31 0
If there is no value in database it should print null but the issue is for the month of feb we don't have 31 but in my report it is printing 0 instead of null values similarly for april also it is printing 0 in 31 row instead of null.. Is there any way that I can do this in crystal report.
Thanks

One of the options is a check box for 'convert NULL values to Default'.

For a numerical field the default is 0, so be sure that option is unchecked ( not sure which menu item it is under, but it is there - under report options, I think)
