Month number must be between 1 and 12

Month number must be between 1 and 12

Month number must be between 1 and 12

Using Crystal CR Developer version and a MS SQL database

Was using this formula in Crystal version 7.0 without any issues but in version 14 it throws the error "Month number must be between 1 and 12".

The formula is: {@DateClosed} in Date (Year (CurrentDate),Month (CurrentDate)-1 , 16) to Date (Year (CurrentDate),Month (CurrentDate) ,1 )-1

When checking the formula it is highlighting this part "Date (Year (CurrentDate),Month (CurrentDate)-1 , 16)"

I suspect the issue is with "Month (CurrentDate)-1" since this is month 1 when it subtracts 1 it leaves 0.

Apparently Crystal 7 was smart enough to know this is a date and when you are in month 1 that subtracting 1 is 12 not 0.

Is there another data function I should be using that know when in month 1 subtracting 1 is 12 not 0?

Thanks Bennie

RE: Month number must be between 1 and 12

Sounds like you need use the datediff or dateadd functions. They handle the month change nicely. I am not sure what you are trying to accomplish with your formula.

Replace Date with Dateserial.
