v Column??? In an interview, asked if i knew it...HELP

Hello,

I had an interview for an Assistant Category Manager job and one of the questions was whether I knew how to do "V Columns" (or maybe VLookup, if there is no such thing as a VColumn) where you take information from one worksheet and move it onto another sheet to comparatively analyze the two data statistically(?????). The job requires that I use access and excel to analyze raw numbers to come up with trends and such...What the heck could they have been talking about? I'm trying to find out so I can let the interviewer know that I've learned how to work with V Columns!

Thanks!

EDIT: Could It have been VLookup that they had said?
