Vlookup error

Hello,


I am having this error when I use the vlookup function, here is what I have:

Cell A Cell B

EDI 2222
EDI 2222
EDI 2222

I am using these formula =VLOOKUP("EDI",A2:B13,2) ..... this is the result 2222, which is good BUT when I use =VLOOKUP("NON-EDI",A2:B13,2) should return error or nothing instead of that is returning 2222 eventhought the text "NON-EDI" is not in cell A.. Do you know what is happening, what can I do???

Thanks
