I have a formula field that calculates a date.
I have a picklist field with numbers (representing number of days).
I need a formula that lets me take the date - days and return a date.
This simple formula did not work:
Service_End_Date__c - Cancellation_Notice__c
as it returned this error on the Cancellation_Notice_c (picklist) field:
Error: Incorrect parameter for function -(). Expected number, date, datetime, received text.
