I'm using an Append Query and want to change if it says F to Female and M to Male. My current formula says: IIf([Gender]="F","Female","Male") but when I try to run the query it comes up with the error message: Syntax error (comma) in query expression. I've tried putting a ; instead of a , as someone else suggested but still doesn't work. Any ideas?! It's driving me crazy! (I am a complete novice when it comes to Access) thanks
