Obviously there's column A and column B... If I'm player A, is that where i enter the draft numbers I'm giving up (hence putting the draft numbers i'm getting in column B), or is column A where I'm putting the draft #s I'd be getting (hence putting the draft picks I'd be giving up in colum B)... It doesn't seem to explain that very clearly... Thanks for the help!

If you are player A, put the draft numbers that you would be giving up in column A. Put the draft numbers that you are being offered into column B. The calculator will then let you know if you should make the trade or not.
