Scores posted on 'games' sheet, sent to 'matches & games' sheet, find winner or indicate 'tie', and show names. I haven't been able to always indicate 'tie' when it's with player on same team. Found winner using 'max', but can't seem to show name of that winner. This is a re-post, since my attachment first time didn't; attach that is. Here's hoping.
