Do you any idea why I might be receiving this message: We were unable to insert a Case with a numeric value Engineering Req Number.? I followed your example and also tested. It works as expected for me. Thank you.
Maybe because your Salesforce Org's storage exceeded it's limit ,that's why it's not accepting any data. Same as mine, what i did, i just logged in on another Org and tried that challenge again.
AND(NOT( ISNUMBER(EngineeringReqNumber__c)) , NOT( ISBLANK(EngineeringReqNumber__c) ))
