that it's probably not a good idea to immediately tell them where they messed up. Some people just need to work formulas out on their own. Because if you do tell them they need to delete a double comma in an 'if' statement or add a closing parenthesis for an 'and' statement, you're likely to get rolling eyes, an "I know" or some other snippy response.
In other words
=if(or(Auditor="rolling eyes",Auditor="I know",Auditor="snippy response"),"Bob is a back sheet driver","Bob let them figure it out on their own")
