Check number against list in Excel

[OP Nashy 800]

Alright. Here's what I need to do:

Type a number in a cell, and it checks against a list in another sheet, and displays in another Cell YES or NO.

What's the formula for this?

you can use the 'match' function (for match type, you can use '0') or vlookup (for column index, put '1', since your list has only one column). now, if the lookup value isn't contained in the list, you'll get a '#N/A' error. put all this together with an if-statement: =IF(ISERROR(MATCH(A1,LIST,0)),"NO","YES").
