I work in a school and I'm trying to create a monthly student birthday report. I want the report be grouped by month. The database I am using records date of birth in one field (MM/DD/YY). The formula I am using is "If {demogrph.dm_dob}[1 to 2] = "01" then "January", "If {demogrph.dm_dob}[1 to 2] = "02" then "February", etc.. The formula editor returns that "A string or an array of values is required here" before the field name. I am a relatively new Crystal user. Any help is appreciated.
