i've been working through salesforce trialhead modules and up until the error i came across today i can usually figure out my mistake. i'm on the creating validation rules exercise which is under "formulas & validation" module. i've started over twice and continue to get this same error. can anyone enlighten me on what i'm doing wrong? Here's the error - There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [MailingPostalCode__c, ShippingPostalCode__c]: [MailingPostalCode__c, ShippingPostalCode__c]
