It’s missing an opening parenthesis, and it’s got an an unparsed date string.

You need to use DATETIME_PARSE() to parse the string into a DateTime object to compare with your Date field.

Also, you may want to use the IS_AFTER() date comparison function.

I think this should be your equivalent formula:

IF(

   IS_AFTER(

      {purchase-date},

      DATETIME_PARSE("02/01/2020", 'MM/DD/YYYY')

   ),

   "Yes",

   "No"

)

Thanks you very much

You’re welcome
