got my first shot at impressing the big boss

well, I know they've been watching me but.... my trainer told the big boss I was good at the computer and I am a spreadsheet guru (mostly true). The big boss asked me how to do something in Excel and I told him I would get him the instructions.... now I have to figure it out!!! Anybody know how to use a date field with color changing alerts as the date approaches? lol, it's all good. I'm willing to bet that he knows the answer and is testing me. They do dumb stuff like that here. He'll have my answer in 24 hours no matter. Admin here I come!
