Hello All and thank you in advance for any help.
I am using CR 11.

I am running reports that I wrote from a server that auto-runs reports for our managers. Recently I got an error that the report failed because the month number needed to be between 1 and 12.
I am curious because I have used this formula
    MonthName (Month (CurrentDate)-1 )
in the past to show the month before on the report. Now it is showing an error. I have searched the posts and could not find any information on this.
Thank you all
