Sorry about the title...I'm sure it is confusing!

This is what Iwant to do: I want to assign mentors to mentees and have a datasheet that shows each pairing. (think teachers to students). I have a list of mentors and a list of mentees and after evaluating the mentee applications, we will manually assign them to a mentor. I essentially want one data sheet that shows clearly which mentor has been assigned to which mentee, along with some other pertinent data, also in the data sheet. I was thinking vlookup would be the key, but don't think that is the answer. Help!
